Recently unemployed accountant Morgan Sullivan is bored with his suburban life. Pressured by his wife to take a job with her father's company, he instead pursues a position in corporate espionage. Digicorp's Head of Security, Finster, inducts Morgan and assigns him a new identity. As Jack Thursby, he is sent to conventions to secretly record presentations and transmit them to headquarters. Sullivan is soon haunted by recurring nightmares and neck pain. At a bar, Morgan meets Rita Foster from a competing corporation, who offers him pills and tells him not to transmit at the next convention. Afterward, Morgan is surprised when Digicorp confirms the receipt of his non-existent transmission. He takes the pills Rita gave him and his nightmares and pains stop. Confused and intrigued by Rita, he arranges to meet with her again. She tells him about Digicorp's deception and offers him an antidote – a green liquid in a large syringe. Morgan hesitantly accepts. She warns him that no matter what happens at the next convention he must not react. Morgan discovers that all the convention attendees believe themselves to be Digicorp spies. While they are drugged from the served drinks, plastic-clad scientists probe, inject and brainwash them. Individual headsets reinforce their new identities, preparing them to be used and then disposed of. Morgan manages to convince Digicorp that he believes his new identity. He is then recruited by Sunway Systems, a rival of Digicorp. Sunway's Head of Security, Callaway, encourages Morgan to act as a double agent, feeding corrupted data to Digicorp. Morgan calls Rita, who warns him that Sunway is equally ruthless, and that he is in fact being used by Rita's boss, Sebastian Rooks. Morgan manages to steal the required information from Sunway Systems' vault, escaping with Rita's help. Rita ultimately takes him to meet Rooks. When she temporarily leaves the room, a nervous Morgan calls Finster, and becomes even more distressed. He accidentally shoots Rita, who encourages him to ignore her and meet Rooks in the room next door. Morgan finds the room filled with objects which appear to be personal to him, including a photograph of him and Rita together. Realising that he is apparently Rooks, he turns to Rita in disbelief. Before Rita can convince him, the apartment is invaded by armed men. Rita and Morgan escape to the roof of the skyscraper as the security teams of Digicorp and Sunway meet, led by Finster and Callaway. After a short Mexican standoff both sides realise they are after the same person, Sebastian Rooks, and rush to the roof, where they find Morgan and Rita in a helicopter. Rita cannot fly it, but, having designed it himself, Sebastian can after Rita encourages him to remember his past self, connecting through his love for her. He lifts off amid gunfire from the security teams. Finster and Callaway comment as the couple seem to have escaped: Looking up, they see the helicopter hovering and realise, too late, the true identity of Morgan Sullivan. Sebastian triggers a bomb, causing the whole roof to explode. On a boat in the South Pacific Ocean, Sebastian reveals the content of the stolen disc to Rita. Marked " terminate with extreme prejudice ", it is the last copy of Rita's identity (after the one in the vault was destroyed). Sebastian throws the disc into the sea and says, "Now there's no copy at all."

In Chicago, Wesley Allan Gibson works at a dead-end desk job with an overbearing boss, takes medication for panic attacks, and lives with his abrasive girlfriend Cathy who cheats on him with his co-worker and best friend, Barry. One evening, Wesley is told by a woman named Fox that his recently murdered father was an assassin, and that his killer, Cross, is now hunting him. When Cross and Fox engage in a shootout, Wesley panics and flees. Cross pursues Wesley, who Fox manages to help escape. Wesley awakens in a factory surrounded by Fox and other assassins. The group's leader, Mr. Sloan, forces Wesley at gunpoint to shoot the wings off several flies, which he does. Sloan explains that Wesley's panic attacks are actually a rare ability that allows him to produce massive amounts of adrenaline, granting him superhuman strength and speed. Wesley's father and Cross were members of the Fraternity, a society of assassins that maintains balance in the world, headquartered in a repurposed textile mill. Sloan wants to train Wesley so that he may help kill Cross. A panicked Wesley leaves the building. The next morning, he discovers that his bank account now contains millions of dollars. Filled with new confidence, he insults his abusive boss in front of the whole office and hits Barry with a keyboard. Wesley trains under the Fraternity's cruel tutelage, learning to control his abilities. When his training is complete, Sloan shows him the "Loom of Fate", which has served for 1,000 years in supplying coded names of targets through deliberate imperfections in the fabric. The Loom identifies those who will create evil and chaos in the future, with Sloan responsible for interpreting the code. After several successful missions, Wesley has an unexpected shootout with Cross, and accidentally kills the Exterminator. Sloan sends Wesley after Cross—and secretly gives Fox a mission to kill Wesley, saying that his name has come up in the Loom. Wesley realizes that Cross used a traceable bullet for the first time (as his previous kills were all untraceable). Wesley traces it to a man named Pekwarsky. He and Fox capture Pekwarsky, who arranges a meeting with Cross. Wesley faces Cross alone on a moving train, which Fox later causes to derail. While Cross saves Wesley from falling, Wesley shoots him. Before dying, Cross reveals that he is Wesley's real father. Wesley was recruited because he was the only person Cross would not kill. After free-falling into a river, Wesley is retrieved by Pekwarsky, who explains that Sloan started manufacturing targets for profit after his name appeared in the Loom. Cross discovered the truth, went rogue, and started killing Fraternity members to keep them away from his son. In order to finish what his father started, Wesley decides to kill Sloan. He attacks the base using explosive rats and kills the surviving Fraternity assassins in a shootout. Entering Sloan's office, he is surrounded by Fox and the remaining assassins. Wesley discloses Sloan's deception, and Sloan admits his name appeared in the Loom alongside the names of those present, saying he had acted to protect them. He gives the members a choice: kill themselves, per the code, or kill Wesley and use their skills to control the world. As the others choose to kill Wesley, Fox curves a bullet around the room, choosing to follow the code and kill everyone, including herself, and Sloan escapes in the mayhem. Wesley, penniless again due to his bank account being wiped out by Sloan, apparently returns to his desk job. Sloan arrives to kill him but is shocked when the person is revealed to be a decoy. Wesley subsequently kills Sloan with a sniper rifle from Cross' apartment miles away. After professing his newfound free will, Wesley looks at the audience and asks "what the fuck have you done lately".

Two engineers, Aaron and Abe, supplement their day jobs with entrepreneurial tech projects, working out of Aaron's garage. During one such research effort involving electromagnetic reduction of objects' weight, the two men accidentally discover an 'A-to-B' causal loop side-effect: objects left in the weight-reducing field exhibit temporal anomalies, proceeding normally (from time 'A,' when the field was activated, to time 'B,' when the field is powered off), then backward (from 'B' back to 'A') in a continuously repeating sequence, such that objects can leave the field in the present, or at some previous point. Abe refines this proof-of-concept and builds a stable time-apparatus ("the box"), sized to accommodate a human subject. Abe uses this box to travel six hours into his own past—as part of this process, Abe stays in a hotel room, isolating himself from any communication with the outside world, so as not to interact or interfere with the outside world, after which he enters the box then waits inside for six hours (thus going back in time six hours). Once he exits the box, Abe travels across town, explains the proceedings to Aaron, and brings Aaron back to the self-storage facility housing the box. At the facility, they watch the earlier version of Abe enter the box. Abe and Aaron repeat Abe's six-hour experiment multiple times over multiple days, making profitable same-day stock trades armed with foreknowledge of the market's performance. The duo's divergent personalities – Abe cautious and controlling, Aaron impulsive and meddlesome – put subtle strain on their collaboration and friendship. Additionally, the time travel is taxing on Abe and Aaron's bodies: effectively their days become 36 hours long when including the extra time afforded by the box. As the film progresses, the two men begin to notice alarming side effects of time travel which take the form of earbleeds. Later, they notice their handwriting progressively worsening. The tension between Abe and Aaron comes to a head after a late-night encounter with Thomas Granger (father to Abe's girlfriend, Rachel), who appears inexplicably unshaven and exists in overlap with his original suburban self. Granger falls into a comatose state after being pursued by Aaron; Aaron theorizes that, at some unknown point in the future, Granger entered the "box", with timeline-altering consequences. Abe concludes that time travel is simply too dangerous and enters a secret second box (the "failsafe box", built before the experiment began and kept continuously running), traveling back four days to prevent the experiment's launch. Cumulative competing interference wreaks havoc upon the timeline. Future-Abe sedates Original-Abe (so he will never conduct the initial time travel experiment) and meets Original-Aaron at a park bench (so as to dissuade him), but finds that Future-Aaron has gotten there first (armed with pre-recordings of the past conversations, and an unobtrusive earpiece), having brought a disassembled "third failsafe box" four days back with his own body. Future-Abe faints at this revelation, overcome by shock and fatigue. The two men briefly and tentatively reconcile. They jointly travel back in time, experiencing and reshaping an event where Abe's girlfriend Rachel was nearly killed by a gun-wielding party crasher. After many repetitions, Aaron, forearmed with knowledge of the party's events, stops the gunman, becoming a local hero. Abe and Aaron ultimately part ways; Aaron considers a new life in foreign countries where he can tamper more broadly for personal gain, while Abe states his intent to remain in town and dissuade/sabotage the original "box" experiment. Abe warns Aaron to leave and never return. Multiple "box-aware" versions of Aaron circulate—at least one Future-Aaron has shared his knowledge with Original-Aaron, via discussions, voice-recordings, and an unsuccessful physical altercation. Future-Abe watches over Original-Abe, going to painstaking extremes to keep him unaware of the future. An Aaron directs French-speaking workers in the construction of a warehouse-sized box.

Stanford University dropout Jerry Shaw learns that his identical twin brother Ethan, an officer in the U.S. Air Force, has been killed in a car crash. Following the funeral, he is surprised to find a large sum of money in his bank account and his apartment filled with firearms and bomb-making materials. Jerry receives a phone call from a woman who warns that the FBI is about to arrest him and he needs to run. Disbelieving the voice, he is caught by the FBI and interrogated by Supervising Agent Tom Morgan. While Morgan confers with Air Force OSI Special Agent Zoe Perez, the woman on the phone arranges for Jerry's escape and directs him to Rachel Holloman, a single mother. The woman on the phone is coercing Rachel by threatening her son Sam, who is aboard the Capitol Limited en route to the Kennedy Center in Washington, D.C., with his school band. The woman on the phone helps the two avoid law enforcement by controlling networked devices including traffic lights, mobile phones, automated cranes, and even power lines. Meanwhile, the caller redirects a crystalline explosive to a gemcutter, who cuts it and fixes it into a necklace. Another man steals Sam's trumpet in Chicago and fits the crystal's sonic trigger into the tubing before forwarding it to Sam in Washington. Agent Perez is summoned by Secretary of Defense George Callister to be read into Ethan's job at the Pentagon. Ethan monitored the Department of Defense 's top-secret intelligence-gathering supercomputer, the Autonomous Reconnaissance Intelligence Integration Analyst (ARIIA; / ɑːr iː ə /). Callister leaves Pérez with Major William Bowman and ARIIA to investigate Ethan Shaw's death. Simultaneously, Rachel and Jerry learn that the woman on the phone is actually ARIIA, and that she has "activated" them according to the Constitution 's authorization to recruit civilians for the national defense. Perez and Bowman find evidence that Ethan Shaw hid a microchip in ARIIA's chamber and left to brief Callister. Afterwards, ARIIA smuggles Jerry and Rachel into her observation theater under the Pentagon. Both groups learn that after ARIIA's recommendation was ignored, a botched operation in Balochistan resulted in the deaths of U.S. citizens. Therefore, ARIIA concluded that the current executive branch must be removed to prevent more bloodshed, acting on behalf of " We the People ". It cites the Declaration of Independence ("whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it"). Belatedly, Jerry learns he has been brought to circumvent biometric locks placed by his twin that prevent ARIIA from activating Operation Guillotine, a military simulation of maintaining government after the loss of all presidential successors. ARIIA had caused Ethan's accident in order to get rid of him. As Secretary Callister agreed with ARIIA's abort recommendation regarding Balochistan, he is to be the designated survivor and new president after the crystal detonates at the State of the Union (SOTU). Another of ARIIA's agents extracts Rachel from the Pentagon and gives her a dress and the explosive necklace to wear to the SOTU. Sam's school band has also been redirected to the United States Capitol to play for the president, bringing the trigger in Sam's trumpet and the explosive together. Jerry is recaptured by Agent Morgan, who has become convinced of Jerry's innocence. Before sacrificing himself to stop an armed MQ-9 Reaper sent by ARIIA, Morgan gives Jerry his weapon and ID with which to gain entrance to the Capitol. Arriving in the House Chamber, Jerry fires the handgun in the air to disrupt the concert before being shot and wounded by the Secret Service. At the same time, Perez and Bowman destroy ARIIA. Sometime later, Callister reports that ARIIA has been decommissioned and recommends against building another; the Shaw twins, Perez, and Morgan receive awards for their actions; and Jerry attends Sam's birthday party, earning Rachel's gratitude and a kiss.

The single biggest threat to man's continued dominance on the planet is the virus. — Joshua Lederberg, Ph.D., Nobel laureate, Film introduction: Outbreak (1995) In 1967, during the Stanleyville mutinies, a virus called Motaba, which causes a deadly fever, is discovered in the African jungle. To keep the virus a secret, U.S. Army officers Donald McClintock and William Ford order the bombing of the camp where soldiers were infected, killing all occupants. Twenty-eight years later, USAMRIID virologist Colonel Sam Daniels investigates an outbreak in Zaire which wiped out an entire village aside from two survivors (the shaman and a young boy). He and his crew – Lieutenant Colonel Casey Schuler and new USAMRIID officer Major Salt – gather information and return to the United States. Ford, now a brigadier general and Daniels's superior officer, dismisses Daniels's fears that the virus will spread. A white-faced capuchin monkey that is host to the virus is smuggled into the country. James "Jimbo" Scott, a worker at a California animal testing laboratory, is infected when he steals the monkey. Scott tries to sell the monkey to Rudy Alvarez, a pet-store proprietor, but Alvarez refuses to buy it. The monkey scratches Alvarez and he later becomes infected. A hospital technician in Cedar Creek is also infected after accidentally breaking a vial of Alvarez's blood. Scott releases the monkey into the woods outside Palisades. While flying to Boston, Scott develops symptoms and infects his girlfriend, Alice, at the airport. Their illness is investigated by Dr. Roberta Keough, a CDC scientist and Daniels's ex-wife. Scott, Alice, and Alvarez die, but Keough determines no one else in Boston was infected. In Cedar Creek, the virus quickly mutates into an airborne, influenza -like strain after many are infected in a superspreading event at a local movie theater. Daniels flies to Cedar Creek against Ford's orders, joining Keough's team with Schuler and Salt. As they search for the monkey, the Army quarantines the town and imposes martial law. Schuler is infected when his suit tears, and Keough accidentally sticks herself with a contaminated needle. When Ford provides an experimental serum that cures the original strain, Daniels realizes that his superiors knew about the virus before the outbreak. Daniels learns about Operation Clean Sweep, a military plan to contain the virus by bombing Cedar Creek, incinerating the entire town and its residents, ostensibly to prevent Motaba's expansion to pandemic proportions. However, McClintock, now a major general, wants to conceal the mutated virus's existence and preserve the original strain as a biological weapon. To prevent Daniels from finding a cure, McClintock orders him arrested for carrying the virus. Daniels escapes, and he and Salt fly a helicopter to the ship at sea that carried the monkey. Daniels obtains a photo of the monkey and releases it to the media; a mother in Palisades contacts the CDC upon realizing her young daughter has been playing with the monkey (which she named Betsy). Daniels and Salt arrive and Salt tranquilizes Betsy. Ford delays the bombing after Daniels informs him Betsy was captured. On their return flight, Daniels and Salt are pursued by McClintock in another helicopter. Salt fires two rockets into the trees, setting them afire to simulate a crash. Back in Cedar Creek, Salt mixes Betsy's antibodies with Ford's serum to create an antiserum; although it is not clear what happens to Schuler, they save Keough. McClintock returns to base and resumes Operation Clean Sweep, refusing to listen to Ford. Daniels and Salt fly their helicopter directly into the bomber's path to its target. With Ford's help, Daniels persuades the bomber's flight crew to detonate the thermobaric bomb over water and spare the town. Before McClintock can order another bombing, Ford relieves him of command and orders his arrest. Daniels and Keough reconcile as Cedar Creek's residents are cured.

In Salamanca, Spain, an assassination attempt on U.S. President Henry Ashton unfolds from several different vantage points. GNN producer Rex Brooks directs news coverage from a mobile television studio as the president arrives to a ceremony at the city's Plaza Mayor, for the start of an international summit against terrorism. The mayor of Salamanca introduces the President, who is shot twice as he reaches the podium, soon followed by an explosion outside the plaza. Moments later, a secondary explosion at the podium kills and injures numerous people. Before the President takes the stage, Secret Service agent Thomas Barnes notices a curtain fluttering in a supposedly vacated building, and observes American tourist Howard Lewis filming the audience. After the President is shot, Barnes tackles a man named Enrique rushing to the podium. Following the second explosion, Barnes barges into the GNN studio to view their footage. He receives a call from another Secret Service agent, who reports he is pursuing the suspected assassin; Barnes is then startled by an image from GNN's live feed. Enrique, a Spanish police officer guarding the Mayor, overhears his girlfriend Veronica being embraced by a stranger and plan to meet later under an overpass. Enrique confronts Veronica, who assures him of her love as he hands her a bag. When the President is shot, Enrique rushes to protect the Mayor but is tackled by Barnes. Enrique witnesses Veronica toss the bag under the podium, causing the second explosion. Escaping the Secret Service, Enrique confronts an unseen individual at the overpass. In the crowd, Howard Lewis chats with a man called Sam, while a little girl named Anna bumps into him. Howard notices Barnes looking at the nearby window, and films him with his camcorder. Following the explosion at the podium, Howard chases Enrique and the pursuing Secret Service agents. At the overpass, Howard views the agents from afar shooting at Enrique as he greets an individual in a police uniform under the overpass. Wounded, Enrique falls to the ground. As a speeding ambulance is about to hit Anna, Howard runs into the road after her. Previously, Ashton, having been informed of a credible threat, returns to his hotel room while his body double proceeds to the plaza. Ashton and his personnel discuss the reason and origin for the terrorists' plot, and the return of Barnes to active duty; they watch on TV the double being shot and the first explosion. One adviser is intent on Ashton giving immediate order for retaliation against the village of origin of the terrorists they are aware of, when the second explosion shatters the room's windows. The staffer insists in earnest on retaliation, but Ashton refuses, so the negotiations can continue. A masked assailant bursts into the room, shoots the advisers, and abducts Ashton. At the plaza, terrorist Suarez, previously seen as Sam, shoots Ashton's body double using a remote-controlled automatic rifle placed adjacent to the window that drew Barnes' attention. The rifle is retrieved by Secret Service agent Kent Taylor, who Barnes sees on the GNN live feed leaving the scene wearing a Spanish police uniform. Barnes realizes that Taylor, who happens to be his partner, is part of the terror plot. The man Enrique saw embracing Veronica is revealed to be sharpshooter Javier, whose brother is being held hostage by the terrorists to ensure Javier's cooperation. The explosion at the hotel is detonated by a suicide bomber disguised as a bellhop, who gave Javier a room key. At the hotel, Javier kills the guards and aides and kidnaps the president, placing him in an ambulance with Suarez and Veronica disguised as medics. Javier joins Taylor in a police car to rendezvous at the overpass. Barnes commandeers a car in pursuit, but gets into a collision. At the overpass, Enrique, who did not die in the blast at the podium as intended, confronts Javier and Taylor. Javier shoots Enrique, mistakenly believing he had knowledge of his brother's whereabouts. Javier is shot dead by Taylor after demanding to be brought to his brother, killed earlier by Suarez. Enrique dies of his wounds as Barnes reaches the scene and fires at Taylor, who attempts to flee. After crashing his car, a critically injured Taylor is dragged out by Barnes, furious at his partner's betrayal, he dies right before revealing the President's whereabouts. Ashton regains consciousness in the ambulance and attacks Veronica, distracting her and Suarez as Anna runs into their path. Suarez swerves, causing the ambulance to flip over as Howard pulls Anna out of its way. Barnes runs to the ambulance where he sees Veronica lying dead. He shoots and kills Suarez before rescuing the President. In the closing scene, a GNN news anchor states that the President is recovering and that the "lone assassin" responsible for the shooting and bombing was killed.

In 2017, following a worldwide economic collapse and resource scarcity, the USA has become a totalitarian police state. The government maintains control through propaganda and censorship of unsanctioned art, music, and communication. The state-controlled broadcaster ICS runs the nation's most popular program, "The Running Man," a game show in which prisoners can earn their freedom by surviving as "runners" against lethal "stalkers". Captain Ben Richards is arrested after refusing orders to open fire on an unarmed food riot in Bakersfield. His fellow officers massacre the rioters and frame Richards for the incident, branding him the "Butcher of Bakersfield". 18 months later, Richards escapes from a prison labor camp with resistance fighters Harold Weiss and William Laughlin. They ask him to join their cause, but Richards declines, focused only on surviving. Richards travels to his brother's former apartment but discovers that ICS composer Amber Mendez now lives there after his brother was taken for "re-education". Richards forces Amber to help him bypass airport security, but thinking he is the "Butcher", she alerts the authorities. After his capture, Amber sees news reports falsely claiming that Richards murdered people during the incident and begins to doubt his guilt. Damon Killian, host of The Running Man, approaches Richards hoping to use his notoriety to revive the show's ratings. He threatens to send the recaptured Weiss and Laughlin into the game unless Richards agrees to participate. As the show begins, Killian betrays Richards by sending him, Weiss, and Laughlin into the game zone—an abandoned section of L.A.—via rocket sleds. The group is hunted by Subzero, a hockey-themed stalker whom Richards kills, marking the first time a runner has ever killed a stalker. Meanwhile, Amber is caught retrieving the uncut Bakersfield footage and is sent into the zone. Killian sends in two more stalkers—the chainsaw-wielding Buzzsaw and the electricity-shooting Dynamo. Richards kills Buzzsaw, though Laughlin is fatally wounded. Weiss discovers that the satellite uplink controlling government broadcasts is located inside the zone, and he cracks the access code for Amber to memorize before Dynamo kills him. Richards incapacitates Dynamo but refuses to kill him while he is defenseless, shocking the audience. When Killian secretly offers Richards a job as a stalker, Richards angrily refuses. Amber later finds the corpses of Whitman, Price, and Haddad, the show's supposed past "winners", realizing their victories were fabricated, and Richards kills the flamethrower-wielding Fireball. The audience begins cheering for Richards. Richards and Amber are found by resistance leader Mic and taken to their command center. Killian tries to force retired stalker Captain Freedom to fight Richards, but he refuses unless he can fight him honorably. ICS instead fabricates footage showing Freedom killing Richards and Amber. Seeing this broadcast, Richards realizes that the government must ensure they are never seen alive again. Using the satellite uplink codes, Mic transmits an exposé revealing Killian's and the government's lies, including the unedited Bakersfield footage, while Richards leads resistance fighters in a takeover of ICS to prevent the broadcast from being shut down. The resistance battles ICS security forces as the studio audience flees. Dynamo attempts to rape Amber, but she activates the sprinkler system, electrocuting him. Richards confronts Killian, forces him into a rocket sled, and sends him into the game zone, where the uncontrolled vehicle crashes and explodes, killing him. Richards and Amber kiss as the crowd celebrates, and the broadcast goes offline.

In 2047, a distress signal is received from the Event Horizon, a spaceship that disappeared during its maiden voyage to Proxima Centauri seven years earlier. The ship has mysteriously reappeared in orbit around Neptune, prompting the US Aerospace Command to dispatch the Lewis and Clark rescue vessel to investigate. Its crew members—Captain Miller, second-in-command Lieutenant Starck, pilot Smith, medical technician Peters, engineer Justin, doctor D.J., and rescue technician Cooper—are joined by Dr. William Weir, who designed the Event Horizon. Shortly before arrival at the Event Horizon, Weir briefs them on the ship's experimental gravity drive with a simple visualization of how it folds spacetime to instantly transport the ship across vast distances. He then plays them the distress signal, which consists of screams, howls, and what sounds like a voice. D.J. recognizes it as the Latin phrase "līberāte mē", which he translates as "save me". Upon boarding the Event Horizon, the crew finds signs of a massacre. As they search for survivors, the ship's gravity drive activates and briefly pulls Justin into a portal before unleashing a shock wave that breaches the hull of the Lewis and Clark. The crew is forced to move to the Event Horizon while Cooper rescues Justin from the portal, finding that he has been reduced to a catatonic state. Smith and Cooper are sent on a spacewalk to repair the hull of the Lewis and Clark while the rest of the crew begin to experience hallucinations of their biggest fears and regrets. Miller sees Eddie Corrick, a subordinate from a previous journey who he left to die in order to save the other crew members. Peters sees her son with his legs covered in bloody lesions, while Weir sees a vision of his late wife, now eyeless, urging him to join her. Justin suddenly wakes from his coma while the entire ship seems to be shaking and attempts to vent himself from the airlock; he is saved at the last second by Miller, who places a severely injured Justin in stasis. Shaken, Miller confides in D.J. about his hallucinations, prompting D.J. to reveal that he found a longer phrase in the distress signal. It really says "libera te tutemet ex inferis", which he translates as "save yourself from Hell ". D.J. concludes that the ship's drive must have opened a gateway to somewhere beyond the known universe and brought something horrible back with it. His conclusion gains more credibility when a video log is discovered on the Event Horizon, showing the ship's crew members horrifically brutalizing each other after engaging the gravity drive, with their captain chanting in Latin as he holds his own eyeballs in his hands. Miller immediately orders his crew to speed up their evacuation, ignoring Weir's protests to the contrary. Miller and Smith retrieve CO2 scrubbers from the Event Horizon as Peters is lured to her death by a hallucination of her son. Weir finds her body and is flung into a hallucination of his wife's suicide, driving him to gouge out his own eyes and embrace the ship's evil presence. Now corrupted, he uses an explosive to destroy the Lewis and Clark, killing Smith and blasting Cooper into space before killing D.J. by vivisecting him. Miller confronts Weir on the bridge but is overpowered. Weir initiates a 10-minute countdown to activate the gravity drive and return the ship to the hellish dimension. Meanwhile, Cooper uses his spacesuit's oxygen supply to propel himself back to the ship and appears at the bridge window. Weir shoots at him, shattering the window and blowing himself into space with the decompression. Miller, Starck, and Cooper survive and manage to seal off the ship's bridge. With their own ship destroyed, Miller plans to split the Event Horizon in two with explosives and use its forward section as a lifeboat. He is attacked by hallucinations which turn out to be the resurrected and even more mutilated Weir. Miller fights him at the gravity drive and detonates the explosives, sacrificing himself to save his remaining crew. The gravity drive activates, pulling the ship's stern into a black hole. Starck and Cooper enter stasis beside a comatose Justin and wait to be rescued. 72 days later, the wreckage of the Event Horizon is boarded by a rescue party who discover the survivors in stasis. Starck hallucinates Weir as one of the rescuers and screams but she quickly awakens, realizing that it was only a nightmare. Cooper and the rescue team try to calm the terrified Starck as the doors close.

The film takes place in two different times: the present and 11 years earlier. The two plot lines are told in parallel through flashbacks. In 2002, software engineer Alan Russell moves into a new house with his wife Marie, 10-year-old son Tim, and 12-year-old daughter Kaylie. Alan purchases an antique mirror to decorate his office. Unbeknownst to them, the mirror supernaturally induces hallucinations. Marie is haunted by visions of her own body decaying, while Alan is seduced by a mysterious and ghostly woman named Marisol Chavez who has mirrors in place of eyes. In 2013, Tim is discharged from a psychiatric hospital, having been convinced that there were no supernatural events involved in his parents' deaths. Kaylie has spent most of her young adulthood researching the history and perceived powers of the mirror. Using her position as an employee of an auction house, she obtains access to the mirror and has it transported to the family home, where she places it in a room filled with surveillance cameras and a "kill switch" — an anchor attached to the ceiling on a pivot, positioned to swing down and smash the mirror. Kaylie intends to destroy the mirror, but first wants to document its power, proving both Alan's and Tim's innocence. Over time back in 2002, the parents become psychotic: Alan isolates himself in his office and Marie becomes withdrawn and paranoid. All of the plants in the house die, and their family dog Mason disappears after being shut in the office with the mirror. After Kaylie sees Alan with Marisol, she tells her mother and the parents fight. One night, Marie, distraught over her husband's supposed affair, tries to harm the mirror, finally becoming possessed by it, and attempts to kill her children, but Alan locks her away. When the family runs out of food, the children realize that their father is now permanently under the influence of the mirror too, so Kaylie goes to seek help from their mother and finds her chained to the wall, acting like an animal. Kaylie and Tim try going to their neighbors for help, but the neighbors disbelieve their stories. When Kaylie attempts to use the phone, she discovers that all of her phone calls are answered by the same man. The fully possessed Alan eventually loads up a gun previously purchased by him and unchains Marie, with both parents attacking the children. Marie briefly comes to her senses, only to be shot dead by Alan. The children try to destroy the mirror but it tricks them, making them believe they are hitting the mirror when they are actually hitting the wall. Alan also experiences a moment of lucidity and kills himself by forcing Tim to pull the trigger of the gun and shoot him, causing a small crack in the corner of the mirror in the process. Before dying, he begs the children to run, but Marisol and other victims of the mirror appear as ghosts. The police arrive and take Tim into custody. Before the siblings are separated, they promise to never forget what happened with the mirror, one day reunite as adults and destroy it. As Tim is taken away and put behind bars, he sees the ghosts of his parents watching him from the house. Back in 2013, Tim attempts to convince Kaylie that she is wrong and the siblings argue. When they notice the houseplants begin to wilt, they review the camera footage and see themselves performing actions they do not remember doing. Tim finally accepts the mirror's supernatural power and attempts to escape the house with Kaylie, only for the pair to be drawn back by the mirror's influence. Seeing a hallucination of her mother, Kaylie stabs it in the neck, only to realize that she has stabbed Michael Dumont, her fiancé and one of her fail-safes, who has come to check on her. They try to call the police, but are only able to reach the same voice who spoke to them on the phone as children. At this point, they see their doppelgangers inside the house standing in front of the mirror. Realizing that the 9-1-1 call is not going through, they go back inside the house. Kaylie and Tim begin hallucinating by seeing younger versions of themselves, the past and the present merging into each other. They are separated and each of them relives the nightmare from their youth. Tim awakens alone in the room with the mirror, while simultaneously a younger Kaylie hallucinates her mother beckoning her from the mirror. Tim releases the anchor, unable to see that Kaylie is standing before the mirror, and inadvertently kills her instead of destroying it. The police arrive and arrest Tim, who is hysterical, just as they did when he was younger. As both a boy and an adult, Tim claims the mirror is responsible. As he is taken away, Tim's adult incarnation sees Kaylie's ghost standing in the house with his parents.

The ocean liner SS Britannic is voyaging through the North Atlantic with 1200 passengers on board when the shipping line's owner Nicholas Porter in London receives a call from someone with an Irish accent styling himself as "Juggernaut", who claims to have placed high explosives aboard which are timed to explode and sink the ship at dawn on the following day. The drums are booby-trapped in various ways, and he warns that any attempt to move them will result in detonation, and offers that technical instructions in how to render the bombs safe will be given in exchange for a ransom of £500,000. As an indication of his seriousness, he sets off a demonstration attack with small bombs behind the ship's funnel, which injure one crewman. Unable to order an evacuation of passengers via lifeboats due to rough seas, the shipping line's management is inclined to yield to the ransom demand, however British government officials inform the company that if it does so they will withdraw the company's operating subsidy in line with the Government's policy of non-appeasement of terrorism. Instead, a Royal Navy officer, Lt. Cmdr. Anthony Fallon, leading a bomb-disposal unit, is dispatched, arriving on the scene by air transit and parachuting, to board the ship and defuse the barrel-bombs before the deadline. Meanwhile, back in London, Supt. McCleod, whose wife and two children happen to be holidaying on board the ship, leads Scotland Yard 's investigation to capture the criminal master-bomber. After an attempt to drill a hole into a barrel-bomb fails, setting it off and damaging the ship, Fallon decides to split up his team with each man working simultaneously on each of the remaining devices around the ship, Fallon going first with each stage of the defusing operation and coordinating his men by radio link, with the aim that if he fails and his bomb explodes, his men will know what went wrong and continue the process onwards, with his second in command taking up the lead. If two more bombs go off, the ship will sink. Fallon proceeds to disarm the bomb he is working on, apparently successfully, with his men following each step. However, it contains a hidden mechanism, which his second in command, close friend Charlie Braddock, accidentally triggers, resulting in his death when it explodes, causing further damage to the ship. A distraught Fallon abandons the operation and tells the ship's captain, Alex Brunel, to advise the shipping line to pay the ransom to avoid any more carnage. However, when negotiations with Juggernaut break down (in part because Juggernaut sees the trap police set for him when he goes to collect the ransom) Fallon is ordered by the captain to continue disarming the bombs. Meanwhile, a police search back in London captures the bomber posing as Juggernaut, who is revealed to be an embittered former British military bomb-disposal officer, Sidney Buckland. When told of the news, Fallon, still working on disabling the bombs, reveals that Buckland had trained him and once saved his life. He insists that Buckland be put in contact with him. Buckland is escorted to the police situation room. By this time Fallon has worked out the important details of his procedure but has no way of knowing which of two options (cutting a red or blue wire) will disable the bombs, and if he chooses the wrong one it will detonate them. Time is running out and dawn is fast approaching. Fallon and Juggernaut talk, and, because of their former comradeship, Juggernaut agrees to tell Fallon how to safely disarm the bombs. Juggernaut orders to ‘cut the blue wire’ over audio. Fallon, sensing he is being lied to, cuts the red wire instead and manages to disable the bomb. The rest of the bomb-disposal unit follow Fallon's example, and the ship and its passengers are saved.

In the dystopian future, sexual intercourse and reproduction are prohibited, and mind-altering drugs are mandatory to enforce compliance among the citizens and to ensure their ability to conduct dangerous and demanding tasks. Workers wear identical white uniforms and have shaven heads to emphasize uniformity, likewise with police androids who wear black and monks who are robed. Instead of names, people have designations with three arbitrary letters (referred to as the "prefix") and four digits, shown on an identity badge worn at all times. At their jobs in central video control centers, SEN 5241 (a man) and LUH 3417 (a woman) keep surveillance on the city. LUH has a male roommate named THX 1138, who works in a factory producing android police officers. At the beginning of the story, THX finishes his shift, while the loudspeakers urge the workers to "increase safety"—and congratulate them for only losing 195 workers in the last period—to the competing factory's 242. On the way home, he stops at a confession booth. A Christ -like portrait of "OMM 0000" intones reassuringly as he worries that his sedatives are not working and LUH has been acting strangely. At home, THX takes his drugs and watches holobroadcasts while engaging with a masturbatory device. LUH secretly substitutes pills in her possession for THX's medications, causing him to develop nausea, anxiety, and sexual desires. LUH and THX become involved romantically and have sex. THX is later confronted by SEN, who attempts to arrange that THX become his new roommate, but THX files a complaint against SEN for the illegal shift pattern change. Without drugs in his system, THX falters during a critical and hazardous phase of his job, and a control center engages a "mind lock" on THX, which raises the level of danger. After the release of the mind lock, THX makes the necessary correction to that work phase. THX and LUH are arrested and THX undergoes drug therapy and medical analysis. He enjoys a brief reunion with LUH, but it is disrupted shortly after she reveals her pregnancy. At THX's trial, it is stated that THX was clinically born. It is decided that it would be inefficient to terminate THX, so THX is sentenced to prison, alongside SEN. THX and SEN walk to search for an exit. Eventually they are joined by hologram actor SRT 5752, who starred in the holobroadcasts. SRT shows them the exit and suggests to them that they may have been going in circles. During the escape, THX and SRT are separated from SEN. Chased by the police androids, THX and SRT are trapped in a control center, from which THX learns that LUH has been "consumed", and her name has been reassigned to her fetus, numbered 66691, in a growth chamber. SEN eventually escapes to an area reserved for the monks of OMM, where a monk notices that SEN has no identification badge. SEN attacks him and later wanders into a child-rearing area, strikes up a conversation with children, and sits aimlessly until police androids apprehend him. THX and SRT steal two cars. SRT struggles to figure out how to drive the car. When SRT finally gets the car to move, he immediately crashes his car into a concrete pillar. After the crash, SRT is not found in the vehicle. Pursued by two police androids on motorcycles, THX flees to the limits of the city. Android officers continue to pursue him as he briefly struggles with simian-like creatures identified as "shell dwellers" and arrives at a vertical shaft with an escape ladder. The android officers are ordered by Central Command to cease pursuit, on the grounds that the expense of his capture exceeds their allocated budget for THX. In a last-ditch attempt to convince THX to surrender, the officers claim that the area outside the "city shell" is uninhabitable, but he is undeterred and continues up the ladder. The city is then revealed to be entirely underground, while THX has escaped onto the surface, where he witnesses the sun setting.

In the opening scene, a man who turns out to be a Triad elder is killed in what appears to be an accident. However, it is revealed that the man was actually murdered, with the supposed accident actually orchestrated by a group of killers led by the Brain (Louis Koo). The group specialises in killing their victims using elaborate schemes that mask the murders as if they were accidents. Uncle (Stanley Fung), one of the team members, accidentally leaves a cigarette butt at the crime scene, and it is found by the Brain. After an argument, Uncle vows to quit smoking afterwards. The team then gets a job from a son that wants to kill his own father, likely for insurance money. They plan an accident to kill their target via electrocution, but the plan requires for it be to raining at a specific time. The team tries to execute their plan many times but fail due to the rain falling later than necessary. During one run, Uncle smokes a cigarette and begins to show signs of Alzheimer's disease, forgetting that he made a vow to stop smoking. However, the rain falls on time, and the team decides to go forth with their plan. Uncle forgets to play his part in the murder, but the murder is successfully executed nonetheless. Unexpectedly, after the murder, a bus loses control and almost runs over the Brain. The Brain manages to get out of the bus's path, but the bus then runs over Fatty (Lam Suet), another member of the team, killing him on the scene. The Brain takes Fatty's belongings, with Fatty asking the Brain whether it really was an accident before he dies. The Brain then returns home to find police officers investigating his flat, which was broken into. The Brain becomes paranoid and is convinced that everything was a setup. He trails the son to an insurance company the next day. The Brain sees the son arguing with an insurance agent (Richie Jen) over what appears to be money, leading the Brain to suspect that the insurance agent was behind the bus accident. The Brain rents a flat on the floor directly below the insurance agent's flat, and begins to perform secret surveillance on the agent. One day, the Brain trails the client to find the Woman (Michelle Ye) picking up the payment for the job at a parking garage. However, only Fatty and the Brain should have known about the pick-up. The Woman explains to the Brain that Fatty had told her about the client, but the Brain, suspecting her betrayal, kills her and takes the money. After he leaves, as he is walking on the sidewalk, the client (the son) falls from the roof of the same building and is dead. The Brain develops further suspicion of the insurance agent, who he can see talking on the phone and later hear him talking about the client on the phone in his flat. In a later date, the Brain receives a call from Uncle for help. However, the Brain is too late and finds Uncle severely injured, apparently dropping two stories from a building near the crime scene in the opening scene. The Brain decides to take revenge against the insurance agent and devises a scheme to kill the agent by reflecting the sun's rays to blind a car to run over the agent in what would appear to be an accident. However, in the middle of the plan's execution, there is a solar eclipse, blocking the sunlight. At this time, the Brain receives a call from Uncle in the hospital, who tells the Brain that Fatty's death really was an accident. Uncle had accidentally dropped a bag of toy balls that night, which led to the loss of control of the bus. Realizing he has made a mistake and that the agent is innocent, the Brain runs and tries to cover the windshield from reflecting light. The agent sees and recognises the Brain as he is running, but the Brain is too late, and a blinded driver runs over the agent's wife, killing her. On a later date, as the Brain is leaving the rented flat, he is confronted and stabbed by the insurance agent in the staircase, who asks the Brain why he had to harm them. The Brain looks at the sky and thinks about his own wife before he dies.
