A botched switching operation by yard hostlers Dewey and Gilleece at an Allegheny and West Virginia Railroad (AWVR) yard in northern Pennsylvania results in a runaway freight train pulled by locomotive 777 (Triple 7) heading south at full throttle, hauling 39 cars. Believing it is coasting, yardmaster Connie Hooper orders Dewey and Gilleece to pursue the train and sends lead welder Ned Oldham ahead in his truck to switch it off the main line. Ned arrives at the switch after the train has passed, and the crew realize that the train is running on full power, let alone, the air brake was not latched on. During this, a train heading in the exact direction, carrying children on a field trip, evaded Triple 7 in the nick of time. Attempts by Dewey and Gilleece to board the train fail, prompting Connie to alert Oscar Galvin, Vice President of Operations, and coordinate with state police to block road crossings. Federal Railroad Administration inspector Scott Werner warns that eight of the 39 cars contain phenol, a highly toxic and flammable chemical, which poses catastrophic risks if the train derails in a populated area. Despite Connie's suggestion to derail the train in unpopulated farmland, Galvin and AWVR's president reject the idea, prioritizing cost-saving measures. Instead, veteran engineer Judd Stewart is sent to slow down Triple 7 with another locomotive to allow AWVR employee and U.S. Marine veteran Ryan Scott to board from a helicopter. The plan fails: Ryan is injured, and Stewart's locomotive derails and explodes, killing him. With Triple 7 approaching a dangerous curve above the heavily populated town of Stanton, Galvin reluctantly approves a controlled derailment near the smaller town of Arklow. Meanwhile, veteran engineer Frank Barnes and rookie conductor Will Colson are moving freight cars with locomotive 1206 going north on the same line as Triple 7. Frank, a seasoned railroad veteran facing his forced early retirement, and Will, who is preoccupied with a restraining order from his wife Darcy over an incident with a former high school colleague and living with his brother, are ordered to pull off into a siding RIP track just before the runaway train races by, smashing through their last boxcar. Frank notices an open coupler on Triple 7's rear car and proposes coupling 1206 to it, using their brakes to slow it before it reaches the Stanton curve. Frank predicts that the portable derailers set up at Arklow will fail due to Triple 7's weight and speed. Galvin dismisses the plan, threatening to fire Frank, Will, and Connie when she supports them. Ignoring him, Frank and Will proceeded with their pursuit. As predicted, the derailers fail, and Triple 7 barrels through them unhindered. Connie and Werner, realizing Frank's plan is their only option, override Galvin and coordinate support. Frank and Will catch up to Triple 7, and Will exits 1206's cab to complete the coupling. When the locking pin will not engage, Will kicks it into place, but his foot gets crushed. Despite the injury, he hobbles back to the cab and takes control of the dynamic brakes while Frank climbs atop the freight cars to manually engage the handbrakes, car by car. Their efforts initially slow Triple 7, but eventually, 1206's brakes burn out, and Triple 7 begins accelerating again. Using the independent air brake, Will and Frank coordinate their brake timing via radio, reducing speed enough to navigate the Stanton curve elevated bridge. However, Frank is blocked from reaching Triple 7's locomotive by a bulkhead flatcar with no walkway. Ned arrives in his truck, speeding alongside the tracks with the police escorting him. Will jumps onto the truck bed, and Ned races ahead of the train. Will leaps onto Triple 7's engine, gains control, and brings the runaway train to a stop. There is later a press conference and Frank, Will, and Ned are commended for their actions. In the aftermath, Will reunites with Darcy and their son, learning that she's pregnant with their second child. Connie arrives to congratulate Frank and Will. Frank is promoted and later retires with full benefits. Will recovers from his injuries and continues working with AWVR. Connie ascends to VP of Operations, while it’s implied Galvin was fired for his poor handling of the incident. Ryan recovers from his injuries, while Dewey is fired and finds work in the fast-food industry.

A cryptic message from the previous M leads MI6 agent James Bond to carry out a mission in Mexico City, foiling a bombing attempt at the Mexico City Metropolitan Cathedral during the Day of the Dead festival. Bond obtains a ring, stylised with an octopus, from deceased attacker Marco Sciarra and uncovers his connection to a secret organisation. In London, Gareth Mallory, the current M, suspends Bond for his unauthorised action. M is engaged in a power struggle with Max Denbigh (whom Bond dubs "C"), the Director-General of the new privately backed Joint Intelligence Service formed by the merger of MI5 and MI6. C campaigns for Britain to join the global surveillance and intelligence initiative "Nine Eyes" and shut down the '00' section. Bond, who was operating on a mission posthumously assigned by the previous M to eliminate Sciarra and track down his employers, goes rogue from MI6, with Eve Moneypenny and Q agreeing to aid Bond covertly. Following the previous M's instructions, Bond attends Sciarra's funeral in Rome and rescues his widow Lucia from assassins. Lucia reveals Sciarra's association with a terrorist network run by Franz Oberhauser, who has been presumed dead for twenty years. Using Sciarra's ring, Bond infiltrates a meeting, where Oberhauser targets the "Pale King" for assassination. Oberhauser recognises Bond, who flees across the city in a modified Aston Martin DB10, pursued by the network's top assassin Hinx. Moneypenny identifies the Pale King as Mr. White, a former member of the organisation's subsidiary Quantum. Bond tracks White down to Altaussee, where he is dying of thallium poisoning. Bond offers to protect White's daughter Madeleine Swann, a psychiatrist who possesses knowledge about "L'Américain". White commits suicide. Bond finds Swann, who is reluctant to trust him until Hinx and his forces abduct her. Bond rescues Swann, earning him her trust. Q reveals Le Chiffre, Dominic Greene, and Raoul Silva as agents of Oberhauser's organisation, which Swann reveals is named Spectre. Swann takes Bond to L'Américain, a hotel in Tangier, where a secret room directs them to Oberhauser's base in the Sahara. Hinx ambushes them en route to the base, but they fight him off and defeat him. Arriving at the base, Bond and Swann confront Oberhauser, who reveals Spectre's involvement in the Joint Intelligence Service and the Nine Eyes programme. C, complicit in Spectre's scheme, plans to give Spectre unrestricted access to intelligence gathered by Nine Eyes. After showing Swann a distressing recording of her father's suicide, Oberhauser subjects Bond to neurosurgical torture: he shares the discussion with Bond to Swann, revealing that they became adoptive brothers after Bond's parents died. Believing that his father loved Bond more than him, Oberhauser killed him and staged his death as well. Since then, he founded Spectre intending to target Bond and adopted the name Ernst Stavro Blofeld. Bond and Swann break free, stun Blofeld with an explosive wristwatch, and destroy the base before fleeing to London to prevent Nine Eyes from going online. In London, Bond, Swann, M, Q, Bill Tanner and Moneypenny gather to arrest C, but Swann and Bond are separately abducted by Spectre operatives, while the others proceed with the plan. After Q stops Nine Eyes from going online, a struggle between M and C results in C's death. Bond is taken to the ruins of the old MI6 building, scheduled for demolition after Silva's bombing, where Swann is held captive. Blofeld, who survived the Sahara base's destruction with heavy scarring to his face, gives Bond a three-minute ultimatum to abandon Swann or attempt a rescue and risk death. Bond finds a bound and gagged Swann, and they escape as the building collapses. Bond shoots down Blofeld's helicopter, which crashes onto Westminster Bridge. Blofeld survives and is arrested by M. Later, Bond receives his restored Aston Martin DB5 from Q and drives off with Swann.

In 2012, alien criminal Boris the Animal escapes from a maximum-security prison on the Moon to take revenge on Men in Black (MIB) Agent K, who shot off his arm and arrested him in 1969. He eventually confronts K and his partner Agent J, telling the former that he is "already dead" before leaving. J and K fall out over the latter's efforts to stop him from pursuing Boris and refusing to explain what happened. At MIB headquarters, J's superior, Agent O, denies his request for further information on Boris' apprehension; only revealing that around the same time, K also deployed the ArcNet, an interplanetary shield that prevented the now-extinct Boglodites from invading Earth. Boris obtains a time machine from Jeffrey Price, the son of a fellow prisoner named Obadiah Price, and travels back in time to July 16, 1969, to kill K, altering history. Though J retains his memories, he briefly suffers from strange side effects, which O identifies as signs that the space-time continuum was fractured before Earth is threatened by a Boglodite invasion. Recalling Boris will commit murder on July 15, 1969, J seeks out Jeffrey, obtains his own time machine, and travels back in time to stop Boris. However, he is arrested by a young K, who almost neuralyzes him until J convinces him of his mission. Following a series of clues, the pair reach the Factory, where undercover MIB agent Andy Warhol directs them to an Archanan named Griffin, who can view all possible outcomes and escaped to Earth after the Boglodites destroyed his planet. Sensing the younger Boris' impending attack, Griffin flees, but alludes to his future location. K and J later find Griffin at Shea Stadium and rescue him from the younger Boris. As the present-day Boris arrives in the past and convinces his younger self to join forces with him, Griffin gives the ArcNet to K and J. After deducing the device must be attached to the Apollo 11 rocket to send it into Earth's orbit, J reluctantly reveals K's impending death. With Griffin revealing that only K can successfully attach the device, K encourages J to take the risk. The trio use jetpacks to reach Cape Canaveral, where Griffin advises the pair to tell the truth to the military police instead of neuralyzing them. They are apprehended by the colonel, but Griffin shows him the importance of their mission. The colonel subsequently assists them in reaching the rocket while Griffin leaves, assuring J that history will be restored once K takes Boris' arm. The Borises attack the agents, but they defeat them before K attaches the ArcNet. Present-day Boris falls into the launchpad's flame trench and is incinerated by the rocket's exhaust while the ArcNet is successfully deployed. K reunites with the colonel, but the latter sacrifices himself to save him from the younger Boris, who goads K into arresting him. K refuses, killing him instead. K soon learns the colonel's son, James, was nearby and reluctantly neuralyzes him. Witnessing the events from afar, J realizes the colonel was his father and his younger self's presence kept him from forgetting K. Returning to a restored 2012, J reconciles with K while un-aged Griffin tells the viewers "this is new favorite moment in human history."

Thomas "Tom" Ludlow, an alcoholic undercover detective for the LAPD 's Vice-Special unit, arranges an arms deal with Korean gangsters suspected of kidnapping two teenage girls. He provokes the gangsters into beating him and stealing his car, allowing him to track them to the gang's hideout. Ludlow storms the hideout and kills the gangsters, staging the scene to make the shootings appear justified, and rescues the captive girls. While Captain Jack Wander and the rest of his unit congratulate him, Ludlow is confronted by his former partner, Terrence Washington, who disapproves of the unit's corrupt tactics. Ludlow is later approached by Captain James Biggs of Internal Affairs, but Wander warns that Washington has reported Ludlow to Biggs. Ludlow follows Washington to a convenience store, where they are ambushed by two gunmen under the pretense of a robbery. Accidentally shot when Ludlow returns fire, Washington is killed by the gunmen. Wander advises Ludlow to remove the surveillance footage, telling the press Ludlow was first on the scene but too late to save Washington. Temporarily reassigned to fielding civilian complaints, Ludlow enlists the help of Detective Paul Diskant, determined to find the killers himself. Washington is implicated in stealing drugs from the evidence room and selling them to the gunmen, identified as criminals Fremont and Coates. Joined by a reluctant Diskant, Ludlow brutalizes informants until a drug dealer, Scribble, leads them to the bodies of the real Fremont and Coates in a shallow grave, killed long before Washington. Giving the surveillance footage to Washington's widow, Linda, Ludlow reveals that he lost his own wife and vows to avenge Washington. He and Diskant pose as dirty cops, forcing Scribble to arrange a meeting with the killers masquerading as Fremont and Coates. Diskant recognizes them, but he and Scribble are killed in the ensuing gunfight. Ludlow kills both assailants, but sees on the news that they were Los Angeles County Sheriff's Department deputies. Declared a "cop killer", Ludlow is arrested by fellow detectives Santos and Demille, who admit to killing the real Fremont and Coates and planting evidence to frame them for Washington's murder. Ludlow realizes that Washington was actually informing on Wander, who is really behind the evidence room theft. Before Santos and Demille can execute him, Ludlow manages to break free and kill them both. He saves Linda from Sergeant Mike Clady, sent by Wander to recover the surveillance footage and kill her, subduing Clady and locking him in his trunk. Ludlow confronts Wander at home, handcuffing him after a brawl. Wander confesses that he has incriminating evidence against high-ranking officials to use to become LAPD chief and, eventually, mayor. Revealing a stash of ill-gotten money and blackmail documents hidden inside his walls, Wander declares his actions were for the sake of Ludlow and their unit, but Ludlow shoots him dead. Biggs arrives, admitting he used Ludlow to bring down Wander on behalf of those in power, and tells him that the department still needs him.

Sometime in the 23rd century... the survivors of war, overpopulation and pollution are living in a great domed city, sealed away from the forgotten world outside. Here, in an ecologically balanced world, mankind lives only for pleasure, freed by the servo-mechanisms which provide everything. There's just one catch: Life must end at thirty unless reborn in the fiery ritual of carrousel. In the year of the city 2274, the remnants of human civilization live in a sealed city beneath a cluster of geodesic domes, a utopia run by computer. The citizens live a hedonistic lifestyle, but when they turn 30 must enter the "Carrousel", a public ritual that destroys their bodies, under the pretense they would be "Renewed" or reborn. Each person has embedded in their hand a "life-clock" crystal that changes color as they age, up to their "Last Day". Residents who attempt to flee the city are known as "Runners", and the team of huntsmen known as " Sandmen " are tasked to pursue and terminate them. Sandmen Logan 5 and Francis 7 attend a Carrousel ceremony until they are called to terminate a nearby Runner. Logan finds a pendant symbol among the Runner's possessions. That evening, Logan meets with Jessica 6, a young woman wearing the same symbol. Logan learns from the computer that the symbol is an ankh and related to a place called "Sanctuary", which the Runners appear to be seeking. There are 1,056 Runners not accounted for. The computer orders Logan to find the Sanctuary and destroy it, but must keep this mission secret from the other Sandmen. The computer changes the color of Logan's crystal to flashing red, essentially cutting his life span by four years and close to Last Day, but it does not respond when Logan questions whether he would get his years restored afterward. Logan tells Jessica he intends to be a Runner. In the Cathedral Plaza area, after they confront some hostile youths, Logan tries to help an escaping woman Runner there, but she is killed by Francis, who now considers Logan an enemy. After unsuccessfully trying facial cosmetic surgery, and evading Francis in a sex club, Logan and Jessica meet the underground group, who direct them towards the city gate. Near the surface, they encounter and defeat Box, a robot who was originally designed to capture and freeze marine life for city food, but has since frozen any Runners who have made it that far. Logan and Jessica escape the city, discovering that out of the computer's influence their crystals are now clear-colored. They enter the abandoned overgrown city that was once Washington, D.C. In the ruins of the United States Senate chamber, they encounter an elderly man living with many cats. The man shares what he knows about his life, including that he had biological parents. Logan realizes that Sanctuary does not physically exist, only the idea and concept to give people hope exists. Francis has followed them; he and Logan fight until Francis is mortally wounded. Logan, Jessica and the old man head back to the dome city, but the old man stays outside, while the two re-enter through the underwater tunnels. They shout at the people to stop entering the Carrousel but no one listens to them, and the two are subsequently captured. The computer overloads after scanning Logan's brain multiple times and only getting the message "there is no Sanctuary". Logan is freed and shoots the computer; the whole facility self-destructs and falls violently, causing everyone to panic and flee. Once outside, the people gather round an artificial waterfall pool and meet the old man.

In 2019, Lincoln Six Echo and Jordan Two Delta live with others in an isolated compound. This dystopian community is governed by a strict set of rules. The residents are told that the outside world has become too contaminated to support life with the exception of a pathogen-free island. Each week, one resident gets to leave the compound and live on the island by way of a lottery. Lincoln begins having dreams that he knows are not from his own experiences. Dr. Merrick, a scientist who runs the compound, is concerned so he places probes in Lincoln's body to monitor his cerebral activity. While secretly visiting the off-limits power facility in the basement where technician James McCord works, Lincoln discovers a live moth in a ventilation shaft, leading him to deduce the outside world is not really contaminated. Lincoln follows the moth to another section, where he discovers the "lottery" is actually a system to selectively remove inhabitants from the compound, where the "winner" is then used for organ harvesting, surrogate pregnancies, and other important purposes for each one's wealthy sponsor, of whom they are clones. Merrick learns Lincoln has discovered the truth about his existence, which compels Lincoln to escape. Meanwhile, Jordan has been selected for the island. She and Lincoln escape the facility and emerge in the desert. He explains the truth to Jordan, and they set out to discover the real world. Merrick hires Burkinabé mercenary and former GIGN operative Albert Laurent to find and return them to the compound. Lincoln and Jordan find McCord in a bar, who explains that all the facility residents are clones of wealthy sponsors kept ignorant about the real world and conditioned to never question their environment or history. Merrick explains to Laurent that while the public is told that the clones are kept in a persistent vegetative state, trials had shown that the organs could only survive if the clones had consciousness. McCord provides the name of Lincoln's sponsor, yacht designer Tom Lincoln, in Los Angeles and helps them to the Yucca maglev station, where they board an Amtrak train to Los Angeles before mercenaries kill him. In New York City, Jordan's sponsor, supermodel Sarah Jordan, is comatose following a car crash and requires transplants from Jordan to survive. Lincoln and Jordan evade both the Los Angeles Police Department and the mercenaries and arrive at Tom's house. Lincoln meets Tom, who gives him some explanation about the cloning institute, causing Lincoln to realize that he has gained Tom's memories. Tom seemingly agrees to help Lincoln and Jordan reveal Merrick's crimes to the public, but secretly betrays them to Merrick and Laurent, as he desperately needs Lincoln's liver to survive his cirrhosis. Tricking Lincoln into leaving with him, although Jordan had warned him she believed he was lying, Tom brings him to an ambush that results in a car chase through suburban Los Angeles. It ends with Lincoln tricking Laurent into believing Tom is the clone and killing him, allowing him to assume Tom's identity. Returning to Tom's home, Lincoln and Jordan give in to their romantic urges and have sex. Merrick surmises that a cloning defect was responsible for Lincoln's memories and behavior, resulting in him and every future clone generation to question their environment and even tap into their sponsor's memories. To prevent this, he decides to eliminate the four latest generations of clones. Lincoln and Jordan, however, plan to liberate the other clones. Posing as Tom, Lincoln returns to the compound to destroy the holographic projectors that conceal the outside world. Jordan allows herself to be caught to assist Lincoln's plan. Laurent, who has moral qualms about the clones' treatment after witnessing their fight for survival and learning that Sarah may not survive even with the organ transplants, helps Jordan. Lincoln kills Merrick with a harpoon gun, and the clones are freed, seeing the outside world for the first time. As Laurent seemingly gives up his mercenary life, Lincoln and Jordan sail away in one of Tom's boats together toward an island, fulfilling their dream of one day going to such a place.

In 1980, the aircraft carrier USS Nimitz departs Naval Station Pearl Harbor for naval exercises in the mid-Pacific Ocean. The ship takes on a civilian observer, Warren Lasky — a systems analyst for Tideman Industries working as an efficiency expert for the U.S. Department of Defense — on the orders of his reclusive employer, Mr. Tideman, whose secretive major defense contractor company designed and built the nuclear-powered warship. Once at sea, the Nimitz encounters a mysterious electrically-charged vortex. While the ship passes through it, radar and other equipment become unresponsive. Unsure of what happened to them and without radio contact with U.S. Pacific Fleet Command at Pearl Harbor, Captain Yelland, commander of the aircraft carrier, fears there may have been a nuclear strike on Hawaii or the continental United States. He orders general quarters and launches a RF-8 Crusader reconnaissance aircraft. The aircraft photographs Pearl Harbor, revealing an intact row of U.S. Pacific fleet battleships, of which several were destroyed during the Japanese attack on Pearl Harbor on December 7, 1941. When a surface contact is spotted on radar, Yelland launches two ready alert Grumman F-14 Tomcat fighter jets from VF-84 to intercept. The patrol witnesses the sinking of a civilian yacht by two Imperial Japanese Navy Mitsubishi A6M "Zero" fighters. The F-14s are ordered to drive off the Zeros without firing, but when the Zeros inadvertently head towards the Nimitz, Yelland gives clearance to shoot them down. The Nimitz rescues survivors from the yacht: U.S. Senator Samuel Chapman, his aide Laurel Scott, her dog Charlie, and one of the two downed Zero pilots. Commander Owens, an amateur historian, recognizes Chapman as a politician who could have been Franklin D. Roosevelt 's running mate (and potential successor) during his final re-election bid, had Chapman not disappeared shortly before the Pearl Harbor attack. When a Grumman E-2 Hawkeye scouting aircraft discovers the Japanese fleet task force poised to launch its attack on Pearl Harbor, the Nimitz crew realizes they've been transported in time to the day before the attack. Yelland has to decide whether to destroy the Japanese fleet and alter the course of history or to stand by and allow history to proceed as they know it. The American civilians and the Zero pilot are kept isolated. While being questioned, the Japanese pilot takes an M-16 rifle from one of the guards, kills two U.S. Marine guards, and takes Scott, Owens, and Lasky hostage. He demands access to a radio to warn the Japanese fleet about the Nimitz. Lasky tells Commander Owens to recite the secret plans for the Japanese attack; the dumbfounded Japanese pilot is overcome, shot, and killed by the other U.S. Marines. In the aftermath, Scott and Owens develop an attraction for each other. Chapman is outraged that Yelland hasn't told anyone about the impending Japanese attack, and rebuffs Yelland's claim that the Nimitz is capable of handling any attack. An attempt to warn Pearl Harbor by radio fails when the Navy considers it a prank. Chapman demands to be taken to Pearl Harbor to warn the naval authorities in person. Yelland agrees in front of Chapman, but then orders Owens to fly the civilians and sufficient supplies via helicopter to an isolated Hawaiian island (Niʻihau), assuming they will eventually be rescued. When they arrive, Chapman realizes he has been tricked and uses a flare gun to force the pilot to fly to Pearl Harbor. During a struggle with another crew member, the flare gun discharges, destroying the craft and stranding Scott and Owens on the island. The Nimitz launches a strike force against the Japanese fleet, but the time vortex returns. After a futile attempt to outrun the storm, Yelland recalls the strike force, and the ship and its aircraft return to 1980, leaving the future relatively unchanged. Upon the return of the Nimitz to Pearl Harbor, Pacific Fleet admirals board the ship to investigate its unexplained disappearance. Lasky leaves the ship with Scott's dog, Charlie, and encounters the mysterious Mr. Tideman, whom he recognizes as a much older Owens. He and his wife, Laurel Scott, invite Lasky to join them as they have "a lot to talk about".

Frank Darbo, a devoutly religious short-order cook, recalls his only two good memories from an otherwise disappointing life: marrying his wife Sarah and pointing a police officer in the direction of a man who snatched a woman's purse. He immortalizes these events in two crayon drawings hung on his wall for inspiration. Sarah, a recovering drug addict, has left him for Jacques, a charismatic strip club owner and drug lord who gets her hooked on drugs again. Frank sinks into depression and has a vision wherein he is touched by the finger of God and meets the Holy Avenger, a superhero from a Christian network TV show who tells Frank that God has chosen him for a very special purpose. Frank believes that God has chosen him to become a superhero and goes to a local comic book store for inspiration. His claim that he is designing a new superhero is met with enthusiastic appreciation from the young store clerk, Libby, and he creates a superhero costume before assuming the identity of the "Crimson Bolt". Lacking superhuman abilities, he deals with injustice in his own way, using a pipe wrench to savagely beat people such as thieves, drug dealers, child molesters, and a man who simply cuts in line at the movies. The Crimson Bolt soon becomes a media sensation, initially viewed as a violent psychopath, but he begins to gain public appreciation after the criminal backgrounds of many of his victims come to light. Frank later attempts to rescue Sarah at Jacques' house, but Jacques' thugs recognize him under the costume and shoot him in the leg as he flees while climbing over a fence. A wounded Frank goes to Libby for help. Libby persuades Frank to let her become the Crimson Bolt's "kid sidekick", calling herself "Boltie" and designing a costume of her own. She proves to be more unhinged than Frank, using her superhero guise to nearly kill a man who possibly vandalized her friend's car, and Frank decides to let her go but changes his mind when she rescues him from some of Jacques' thugs at a gas station. Libby soon becomes enamored with Frank, but he turns down her advances, insisting he is still married. Arguing that the rules are different when they are using their superhero identities, Libby rapes Frank while the two are in costume and later claims to have been suffering from sexsomnia. Frank runs to the bathroom and vomits, encountering a vision of Sarah in the toilet. He decides to rescue her from Jacques once and for all. Armed with guns, pipe bombs, and bulletproof vests, Frank and Libby sneak into Jacques' ranch and kill the first few guards they encounter. Frank is shot in the chest and saved by his bulletproof vest, but Libby is shot in the head and killed. Devastated, Frank furiously slaughters all of Jacques' thugs. Inside, Jacques shoots Frank, but Frank gains the upper hand and stabs Jacques to death as a horrified Sarah watches. Frank takes Sarah home and she stays with him for a few months, which Frank surmises is "out of a sense of obligation" for saving her life. One day, Frank returns home to find Sarah has left him again. This time, she overcomes her addiction and uses her experiences to help others with similar problems. She marries a man named Patrick and has four children. Frank is convinced that her children will change the world for the better. Frank, content and living alone with a pet rabbit, looks at his wall of happy memories. The wall is now covered with pictures of his experiences from his time spent with Libby and pictures of Sarah's children, who call him "Uncle Frank". He gazes at Libby's picture as a tear runs down his cheek.

In an Indian village, Buldeo, an elderly storyteller, is paid by a visiting British memsahib to tell a story of his youth. As a younger man, he recalls his village being attacked by Shere Khan the rogue Bengal tiger. The attack leads to the death of a man and the loss of the man's child. The child is adopted by grey wolves in the jungle and grows to be the wild youth Mowgli. Twelve years after, Mowgli is captured by the villagers and taken in by his mother Messua, despite Buldeo's prejudice towards him for being from the jungle. He learns to speak and tries to imitate the ways of humans, and becomes friendly with Buldeo's daughter, Mahala. When Mowgli and Mahala explore the jungle, they discover a hidden chamber in a ruined palace, containing fabulous wealth. Warned by an aged cobra that the wealth brings death, they leave, but Mahala takes one coin as a memento. When Buldeo sees the coin, he resolves to follow Mowgli to the site of the treasure. Mowgli fights and uses a jambiya knife to kill Shere Khan, with some last minute help from Kaa, the Indian python. As he is skinning the body, Buldeo arrives. He threatens Mowgli with his hunting rifle to take him to the treasure, but is attacked by Mowgli's friend Bagheera, the black panther. Buldeo becomes convinced that Bagheera is Mowgli himself, shape-shifted into panther form. He tells the villagers that Mowgli is a witch, as is his mother. Mowgli is chained up and threatened with death, but escapes with his mother's help. However, she and another villager who tries to defend her are tied up and threatened to be burned for witchcraft. Mowgli is followed by the greedy Buldeo and two friends, a pandit and a barber, to the lost city. They find the treasure and leave for the village with as much as they can carry. When they stop for the night, the priest tries to steal the treasure and murders the barber when the barber wakes up. The priest tells Buldeo that the barber had attacked him and that he had killed in self-defense, but Buldeo knows better. The next day, the priest attacks Buldeo while his back is turned, but Buldeo knocks him into the swamp where he is killed by a mugger crocodile. Mowgli tells Bagheera and Grey Brother to chase Buldeo from the jungle, and Buldeo flees for his life, jettisoning the treasure. His pride wounded, a half-crazed Buldeo tries to murder Mowgli and destroy the jungle by starting a forest fire. The wind turns and the fire threatens the village. The villagers flee, but Mowgli's mother and her defender are trapped. Mowgli brings the local elephants including their leader Hathi who help free the captives and rescue the jungle animals from the fire. He is invited to follow them to a new life downriver, but chooses to stay and protect the jungle. The scene returns to the present day, with the elderly Buldeo admitting that the jungle defeated his youthful dreams and destroyed his reputation. When asked how he escaped from the fire and what became of Mowgli and his daughter, Buldeo says that is another story.

Kang Jae-hyeok works at the aging Hanbyul Nuclear Power Plant, which is their namesake town's only source of energy and jobs. Jae-hyeok, who had earlier lost both his father and brother working at the plant in his early years, lives with his mother, sister-in-law, and nephew Min-jae. He expresses his desire to work at a fishing vessel to make money for his family rather than work at the plant, but is discouraged by everyone he knows, including his childhood friend & fiancée Yeon-joo. Pyeong-seok is one of the head operators of the plant, who alongside a coalition of his concerned plant workers and anti-nuclear activists, tries to get the President of South Korea Seok-ko Hang, to shut down the plant due to urgent safety concerns, but they are dismissed by the other senior plant operators, especially the Prime Minister. An earthquake suddenly strikes the town, causing the nuclear reactor to overheat. Due to the plant's aging safety systems, attempts to cool down the overheating reactor are ineffective. Meanwhile, Hang's administration fiercely debates between allowing the reactor to vent radioactive particles into the air to relieve pressure from the core or evacuating large population centers around the plant, before they settle on evacuating residents closest to the reactor. Due to the lack of a contingency plan in place, the only route leading out of town quickly became gridlocked. This critical delay led to the reactor building exploding before the crew could open the pressure release valves themselves, killing or injuring most of the plant workers. Jae-hyeok hauls out his friend Gil-seop and much of the workers out from the plant before he collapses from radiation poisoning. The KCDC quarantines the town's residents not far from the reactor. However. after Yeon-joo gets proof that the reactor exploded and delivers the news, they set up a jammer and locks the evacuees inside the evacuation center as they leave them for dead, except for the junior nurse Mi-sook, who is treating Jae-hyeok and other plant workers. Yeon-joo, along with the town's residents manage to break out from the evacuation center and commandeers one of the buses for their citizens to escape. Despite the firefighters' efforts to cool the reactors, some of the firefighting crew also began experiencing radiation poisoning symptoms as well. Hang, after fallen into depression for the reactor explosion, orders the firefighters to use seawater to decommission the reactors completely. He and Pyeong-seok discovers that there is a growing crack underneath the storage tank in the basement, putting the spent fuel rods in danger of overheating. When the Army 's military engineers refuse to step in, Hang addresses to the nation, requesting aid from the plant workers to perform a dangerous operation of sealing the cracks in the basement. Jae-hyeok bitterly declines, but at the insistence of Gil-seop, he eventually agrees for the sake of the people. He calls a distraught Yeon-joo before he boards on a bus back to the town along with their surviving crew. During their operation, the crack underneath the coolant tank grew bigger and they are ordered to retreat. Jae-hyeok suggests they seal the door and blow up the tank to allow the spent fuel rods to fall into the basement, effectively creating a new tank. However, at the current situation, both of these steps must be executed simultaneously, meaning one will not be leaving out alive. Jae-hyeok, the only person among the group who can operate explosives and having already been too sick from radiation poisoning, volunteers to sacrifice himself, allowing the workers to then seal himself into the waste room before fleeing the area.
