In the year 2017, the United States has fragmented into post-apocalyptic wastelands with a few civilized areas. An ongoing economic crisis has led to the recycling of aging 20th-century mechanical and technological equipment. Society has also become averse to intimacy, as well as both increasingly hypersexualized and bureaucratic. Robotic technology has produced gynoids as substitutes for wives. The declining instances of actual sex among men and women is litigious, with one brothel having lawyers draft up contracts detailing the intended sexual rendezvous. Recycling executive Sam Treadwell owns a Cherry 2000 model as his wife. After she short circuits during sex on a wet kitchen floor, Sam is told by a repairman that she is damaged beyond repair, though her rare and valuable memory disk, which contains her entire personality, can be used in a new body if the same model can be found. A gynoid dealer tells Sam that the Cherry 2000 model is no longer produced and that the only remaining ones are in a defunct warehouse in "Zone 7", a particularly dangerous, lawless area. With Cherry's memory disk stored in a device that plays back Cherry's voice, Sam hires Edith "E" Johnson, a tough tracker, to guide him to the factory. They set off in Edith's heavily modified 1965 Ford Mustang. Entering Zone 7, they encounter Lester, a wasteland overlord with deranged subordinates. Edith and Sam take refuge in an underground reservoir occupied by Six-Fingered Jake, an elderly tracker who was Edith's mentor. When Lester's men attack, the three attempt to escape, but Sam is knocked unconscious and taken to a 1950s-styled motel/village. Ginger, one of Lester's gang, reveals herself as Sam's ex-girlfriend, previously known as Elaine. Lester decides to induct Sam into the group, and Sam, believing that Edith and Jake are dead, goes along for a while. When he witnesses the group sadistically murdering a tracker, Sam decides to escape and runs into Edith and Jake, still quite alive. Jake, who had earlier led Sam to believe that the Cherry 2000 memory disk had been lost, still has it and gives it to Edith while he stays behind to draw off Lester's gang. Sam, a veteran of earlier wars, shows that he is a capable fighter, and Edith begins to have feelings for him. Sam's own growing feelings toward Edith, though, are derailed when he hears Cherry's voice accidentally play on the audio device. Continuing to work their way to the gynoid warehouse, they arrive at a brothel/gas station owned by Snappy Tom, a friend of Jake's, where a dilapidated Aeronca Champion light airplane is stored. Edith repairs the plane using parts from the Mustang. Jake catches up with the group and reminisces with Snappy Tom, but Snappy's live-in girlfriend betrays their location to Lester over the radio and shoots Jake in the back. Edith and Sam manage to escape in the plane. Sam is almost ready to abandon the quest, but Edith is determined to complete her job as a tracker so Jake's death will not become meaningless. As they land, Zone 7 is revealed to be actually the abandoned ruins of Las Vegas and the gynoid "warehouse" is actually a casino. Sam finally finds a functional Cherry 2000 model and activates her with the memory disk; however, being programmed only for home life and sex, the robot is incapable of adapting to the current dangerous situation when Lester and his gang attack. In an extended battle, Sam, Edith, and Cherry climb aboard the airplane, but their combined weight prevents takeoff. Edith jumps out so that Sam and the robot can escape, but Sam realizes that Cherry cannot provide the human interaction that he and Edith have had and turns the plane around. Cherry, programmed to fulfill Sam's wishes, offers to bring him a Pepsi, so he sends her away as he and Edith fight off Lester's gang and take off in the plane. When Lester tries to lasso the plane, he gets caught in the rope and hangs himself from one of the ancient Las Vegas neon casino signs. Edith and Sam kiss as they fly away into the sunset.

In 2021, society is driven by a virtual Internet, which has created a degenerative effect called "nerve attenuation syndrome" or NAS. Megacorporations control much of the world, intensifying the class hostility already created by NAS. Johnny is a "mnemonic courier" who discreetly transports sensitive data for corporations in a storage device implanted in his brain at the cost of his childhood memories. His current job is for a group of scientists in Beijing. Johnny initially balks when he learns the data exceeds his memory capacity even with compression, but he agrees given the large fee will cover the cost of the operation to remove the device. Johnny keeps it secret that he is overloaded; he must have the data extracted within a few days or suffer fatal brain damage and corrupt the data. The scientists encrypt the data with three random images from a television feed. As they transmit these images to the receiver in Newark, New Jersey, they are attacked and killed by yakuza led by Shinji, who wields a laser whip. Johnny battles the yakuza, grabs a fragment of the encryption key images, and escapes. Shinji reports his failure to his superior, Takahashi. Their conversation reveals the yakuza are working on behalf of Pharmakom, a megacorporation. Johnny witnesses brief projections of a female artificial intelligence who attempts to aid him, but he dismisses her. The AI is later identified as Anna Kalmann, Pharmakom's former CEO and founder who became an AI upon her death. In Newark, Johnny meets with his handler Ralfi, who betrays him. Johnny is rescued from the yakuza by Jane, a cybernetically-enhanced bodyguard; members of the LoTeks, an anti-establishment group; and the LoTeks' leader, J-Bone. Ralfi is sliced into pieces when he gets in Shinji's way. Jane takes Johnny to Spider, the doctor who installed Jane's implants. At a clinic, Spider reveals his medical charity was intended to receive the Beijing scientists' data, which is a stolen cure for NAS. Spider claims Pharmakom refuses to release the cure because they are profiting off mitigation treatments. The portion of the encryption images Johnny took plus the piece Spider received are insufficient to decrypt Johnny's mind, so Spider suggests they see Jones at the LoTeks' base. Suddenly, an assassin hired by Takahashi known as "The Street Preacher" attacks them, killing Spider as Johnny and Jane escape. The two reach the LoTek base and learn from J-Bone that Jones is a dolphin once used by the Navy that can help decrypt Johnny's payload. As they start the procedure, Shinji and the yakuza attack the base. Takahashi appears and confronts Johnny, holding him at gunpoint. At the same time, Anna appears and confirms that Pharmakom already had a cure for NAS before Takahashi's young daughter died from the condition eight months prior; Anna is helping out of disgust with her company's actions. Shinji, in a surprise betrayal, shoots Takahashi. Johnny and Shinji fight, culminating with Johnny killing Shinji. Before he dies, Takahashi has a change of heart and turns over a portion of the encryption key to Johnny. This still is not enough to fully decrypt the data. J-Bone tells Johnny that he will need to hack his own mind with Jones' help. Johnny, Jane, J-Bone and the LoTeks defeat the remaining forces sent after them. The Street Preacher arrives, and, after a fight, is electrocuted to death by Johnny and Jane. The second attempt starts, and aided by Anna, Johnny decrypts the data and simultaneously recovers his childhood memories which reveals that Anna is his mother. As J-Bone transmits the NAS cure information across the internet via pirate broadcasts, Johnny and Jane watch from afar as the Pharmakom headquarters goes up in flames. In celebration, J-Bone disposes of the Street Preacher's burnt corpse by tossing it into the waters of Newark.

A young woman named Bugs learns that the Matrix is running old code in a loop, enacting the moment when Trinity first found Neo within the Matrix. Bugs discovers a program embodying Morpheus and helps free him from the simulation. Thomas Anderson is the creator of a video game series called The Matrix, based on his faint memories as Neo. At a coffee shop, he regularly encounters Tiffany, a married mother with no recollection of her past, on whom Anderson based the game character Trinity. Anderson has created a simulation called a Modal to develop game characters. He struggles to separate perceived reality from dreams, a known concern among his co-workers and partner. Thomas's psychoanalyst prescribes him blue pills that he takes each day to suppress the occurrences, but he stops taking them. Meanwhile, as Bugs and Morpheus work to extract Neo from the Matrix, Anderson's business partner regains his memories as Agent Smith, Neo's former nemesis. Neo awakens in a pod and notices Trinity confined in another nearby, before being extracted to Bugs's hovercraft Mnemosyne. Neo is brought to the human city Io, the sister city of Zion, where he reunites with an elderly Niobe. She explains that sixty years have passed in the real world since the Machine War ended, and that Neo's allies, including the original Morpheus, have all died over time. The peace achieved by Neo's sacrifice lasted for many years, but the large number of humans leaving the Matrix created a serious power shortage, causing the machines to fight over limited resources. Soon afterward, Zion was targeted in an attempt to get humans to use as the power supply once more. However, this attempt caused many machines, who still remembered Neo's sacrifice and the promise of peace, to turn on the others in order to protect the humans. This allowed most of Zion's citizens to escape. Io was then founded by both machines and humans who have been working together ever since against the remaining machines who want to return things to the way they were before the war. Niobe refuses to risk Io's safety to help Neo free Trinity and confines him to his quarters. Bugs and her crewmates free Neo and enter the Matrix to contact Trinity. They are attacked by Smith and other exiled programs, including the Merovingian, but Neo and the Mnemosyne crew defeat them as Neo's abilities return. The group leaves and locates Trinity, but before Neo can talk to her, his therapist appears and immobilizes him by manipulating time. He reveals that he is The Analyst, a program designed to study the human psyche. The Analyst explains that after Neo's and Trinity's deaths, he wanted to study Neo's body and his anomalous powers as The One and convinced his superiors to resurrect both of them. He discovered that due to The One's inherent connection to all humanity in the Matrix, manipulating Neo could make the Matrix produce more energy. Moreover, he found that the code anomaly in Neo was shared in his bond with Trinity, and that by suppressing their memories and keeping them close but always apart, the Matrix generated much more energy. Solving the energy crisis put The Analyst in a position to seize power from The Architect, after which he rebuilt the Matrix to control humans with emotional manipulation, claiming that humans generally believe what they want to believe. Neo's liberation destabilized the system and triggered a fail-safe to reboot the Matrix, but The Analyst stalled the reboot by convincing his superiors that threatening to kill Trinity would coerce Neo to return to his pod. Neo and Bugs return to Io and talk to Sati, an exiled program that Neo previously met. Seeking to avenge her parents' deaths at the hands of the Analyst, Sati helps devise a plan to free Trinity. Back in the Matrix, Neo makes a deal with The Analyst: he will return to his pod if he fails to convince Trinity to leave the Matrix. Tiffany reaffirms her identity as Trinity while talking with Neo. Realizing that he has lost, The Analyst attempts to kill her, but Agent Smith appears and attacks him, seeking revenge for his own imprisonment after being restored as a result of Neo's resurrection. Neo, Trinity, and the others escape in their vehicles, chased through the streets by hordes of bot programs and attack helicopters. As the last ones to be extracted from The Matrix, Neo and Trinity become cornered atop a skyscraper. Holding hands, they leap off and Trinity begins to fly, taking them to safety. With Trinity's newfound control over the Matrix, both return to confront The Analyst. They thank him for giving them a second chance by resurrecting them while they also express their contempt. Neo and Trinity fly off into the sky together, making plans to remake The Matrix.

After a successful Sydney bank robbery, with the robbers wearing pig masks and wielding shotguns, the man in charge, "The Boss", plans a further and larger payroll robbery for two days later, worth at least $1.5 million. He hopes that he can trust his less-than-competent gang, headed by Whitey and Moustache, to do the job properly. Anyone who fails will answer to him. Two young BMX experts, P. J. and Goose, meet Judy, who is working as a trolley collector at the Warringah Mall during the school holidays to be able to buy her own BMX bike, and accidentally get Judy fired from her job when they crash into trolleys pushed away by the local "Creep". The three go out in Goose's dad's runabout on the harbour searching for cockles to sell to fix their own crashed bikes, as well as getting Judy her own, and stumble onto and steal a box of police-band walkie-talkies that the bank robbers were hoping to use to monitor police traffic. After stealing the box, the kids pass Whitey and Moustache, who are on their way in their high-powered motorboat to pick it up. Judy, P.J., and Goose sell the walkie-talkies to other kids in the area. The Bayside Police can hear the kids using the walkie-talkies. Judy, P.J., and Goose are also unaware that the robbers know who stole the box. After they are spotted and chased late at night through a cemetery by Whitey and Moustache wearing monster masks (going formal, according to Whitey), they manage to escape. The next day, P.J. and Goose pick up their newly repaired bikes while Judy buys her bike. Judy is caught the next day by Whitey and Moustache while getting a second walkie-talkie for The Creep but escapes with the help of P.J. and Goose. The goons chase the Bandits in a cartoonish chase across various sites around Sydney, including a memorable escape down the Manly Waterworks water slides, complete with BMX bikes. The trio are finally arrested but escape police custody and, with the help of the local kids, launch their plan to foil the planned payroll robbery. Using the walkie-talkies, the Bandits pinpoint the meeting place for the robbers, then proceed to ambush and apprehend the robbers. The Boss, Whitey, and Moustache escape in a removal truck with Judy as a hostage, with P.J., Goose and their BMX friends giving chase. They cause the truck to crash, with police soon arriving to arrest The Boss, Whitey and Moustache. The police build a BMX track as thanks for the capture. In its opening meeting, the BMX Bandits sweep the main awards.

After witnessing crime lord Eddie Kim brutally murder prosecutor Daniel Hayes in a secluded forest in Hawaii, Sean Jones is escorted by FBI agents Neville Flynn and John Sanders on a Boeing 747-400 to testify in a trial against Kim in Los Angeles. Kim arranges for a time-release crate full of venomous snakes to be placed in the cargo hold in an attempt to bring down the plane before it reaches Los Angeles International Airport (LAX). To ensure the snakes indiscriminately attack everybody without the need for provocation, he has one of his henchmen disguised as an airport ground employee spray the passengers' leis with a special pheromone which makes the snakes highly aggressive. The crate opens midway through the flight and the snakes make their way through the cabin, with a viper attacking an electric panel in the process, thus shutting down the power. A cat in the cargo bay, a couple having sex in a bathroom, and a man using another bathroom are the first ones to be killed. The plane's captain, Sam McKeon, investigates the power outage and fixes an electrical short, but is killed by the viper that caused it. Co-pilot Rick, unaware of the snakes, believes Sam has suffered a heart attack and continues toward LAX. Some snakes attack Rick, and while fending them off, he accidentally releases the oxygen masks throughout the plane, causing most of the snakes to drop into the cabin with them. Numerous passengers, including Agent Sanders, are killed when the snakes invade the cabin. The surviving passengers, who have made their way to the front of the plane, put up blockades of luggage in a desperate attempt to stop the snakes. Rick is attacked and the plane starts to descend, causing a food trolley to crash through the luggage blockade. The passengers flee to the upstairs first-class cabin before blocking the stairwell with an inflatable life raft. Flynn and flight attendant Claire regain control of the plane while Rick retakes the controls and has Flynn go into the cargo hold to restore the air conditioning/ventilation system. Flynn contacts FBI special agent Hank Harris on the ground, who gets in touch with ophiologist Dr. Steven Price, Customs' main source for animal smuggling cases. Based on pictures of the reptiles emailed to him via Mercedes's mobile phone, Price believes that Kraitler Mullet, a snake dealer based in the Los Angeles outskirts known for illegally importing exotic and highly dangerous snakes, is responsible. After a shootout, the agents subject Kraitler to tactical interrogation after the latter is injured by a snakebite; with Harris withholding the antivenom, the injured Kraitler finally reveals that Kim hired him to obtain the snakes and exposes more of Kim's schemes of smuggling them on board the flight. Price medicates Kraitler and commands his supplies of antivenom for the victims on the plane based on the list given to him while Harris orders Kim arrested and tried on multiple counts of murder and attempted murder, with the death penalty as an option. Harris contacts Flynn, telling him that antivenom will be ready for the passengers when they land. However, Flynn discovers that the cockpit is filled with snakes and Rick is dead. After a brief discussion, Troy, a bodyguard for rapper Three G's, agrees to land the plane based on his experience playing a flight simulator. After everyone gets prepared, Flynn shoots out two windows with his pistol, causing the plane to depressurize. The snakes are blown out of the cockpit and the lower floor of the plane. Despite his lack of real-world experience, Troy makes an emergency landing and the plane makes it to the terminal. The passengers exit the plane and antivenom is given to those who need it. Just as Flynn and Sean are about to disembark, a remaining snake jumps out and bites Sean in the chest. Flynn draws his gun and shoots the snake, and paramedics rush to a traumatized Sean, who remains unharmed due to a ballistic vest he wore throughout the ordeal after his rescue from Kim's henchmen. As a token of gratitude, Sean later takes Flynn to Bali and teaches him how to surf.

Wu Qianli, commander of the People's Liberation Army 's 7th Company, returns home after the Chinese Civil War. He tells his family that his brother, Wu Baili, was killed in action. Having been allotted land for his service, he promises his parents he will build them a house, but his leave is cancelled when China enters the Korean War. Qianli's younger brother, Wanli, asks to go with, but is refused. On 15 September 1950, where the Battle of Incheon is underway. U.S. aircraft are shown indiscriminately bombing a village in Andong Province, China. The film then jumps to Beijing on 4 October 1950 where the Politburo of the Chinese Communist Party is meeting in Zhongnanhai to discuss the war situation. Mao Zedong asks whether the U.S. Army crossing the 38th parallel means they will also cross the Yalu. The military briefer states that by stationing forces in Taiwan, the U.S. has already invaded China and U.S. forces in Korea threatens China's security. To Qianli's horror, Wanli has enlisted and is stationed in the 7th Company. Wanli gets bullied by the other members of the 7th Company en route to Korea, with Qianli refusing to help him and at first refuses to even give him a rifle. The train is bombed while track is being fixed, forcing the 7th Company to continue on foot while avoiding American aircraft. The 7th Company stumble upon a battle and aid a group of Chinese soldiers. Wanli and Qianli kill four Americans in hand-to-hand combat and avoid being killed by a tank. The 7th Company continues to the front lines, eventually arriving and delivering field radios.The 7th Company is allowed to rest. Mao Zedong's son, Anying, serving under the pseudonym "Liu", helps distribute clothing to them before the company is ordered to the front lines. The Chinese soldiers stay hidden in the mountains, running low on supplies and facing below-freezing temperatures while American soldiers celebrate Thanksgiving in relative comfort and anticipate going home for Christmas. U.S. radio detection detects the headquarters where Anying is stationed and aircraft are sent to bomb the base. While most of the staff take shelter in bunkers, Anying runs back to the base to collect a map and is killed in the bombing. The 27 November offensive begins with Chinese soldiers swarming the positions of the U.S. Army 31st Infantry Regiment at Sinhung-ni. The Americans begin to retreat and Qianli shoots the U.S. commander, Colonel Allan MacLean, but then stops Wanli from executing him. At Hagaru-ri reinforcements are ordered to Sinhung-ni. A USMC Vought F4U Corsair attacks the Chinese forces and drops a smoke marker on the overrun base but is then shot down by a Chinese soldier using a bazooka. Lei Suisheng puts the smoke marker in a jeep and drives off, joining up with the retreating U.S. column. The U.S. bombers destroy the American column and Lei is killed. Hagaru-ri, which is under attack by the Chinese. U.S. forces are forced to retreat by air and land while they are pursued by Chinese forces. The scene then shifts again to the 3rd Company, 3rd Division, 58th Corps on Hill 1071, which is shown holding out against U.S. forces. Yang Gensi, as the last surviving member of his unit, suicidally attacks American tanks with a satchel charge. The retreating U.S. Marine column finds a group of Chinese soldiers frozen to death at their post. General Oliver P. Smith salutes them; his voiceover is heard saying that fighting against such strong-willed men, the U.S. was not ordained to win.The closing scenes show a U.S. mass grave at Hungnam as the city burns during the Hungnam evacuation. Captions state that 105,000 U.S. troops were evacuated by 24 December and that the 9th Corps captured Hungnam. The captions explain the significance of the battle of Lake Changjin, which was a "perfect example for annihilating a U.S. reinforced regiment" and how Chinese forces stopped MacArthur's "presumptuous" plan to end the war by Christmas and "set the stage for the final victory of the War to Resist U.S. Aggression and Aid Korea" despite the deaths of more than 197,000 Chinese.

An interrogator prepares a man to take the stand against mob boss Frank Matajano on an Air Force base. A driver delivers takeout, which is taken to the interrogation room. Once opened, it explodes, killing the witness. In court, a judge places court on recess until the attorney general can bring sufficient evidence against Matajano. The attorney general angrily demands a U.S. marshal, Pat Schiller (Robert John Burke), get evidence in 72 hours to replace the killed witness. On a chain gang, an inmate harasses Luke Dodge (Stephen Baldwin), who fights back. When Charles Piper (Laurence Fishburne) intervenes, the guards chain him and Dodge together, and then Dodge and Piper begin fighting. The guards discuss a plan in hushed tones and change their magazines, but before they do anything, the inmate who attacked Dodge snatches a gun and starts a shootout. During the confusion, Dodge and Piper escape. The cop who arrested Dodge, Matthew 'Gib' Gibson (Will Patton) picks up a magazine at the crime scene. A fellow cop informs him that the attorney general asked him to place Dodge on that chain gang against protocol. Suspicious, he runs off into the woods and finds the third convict, who is shot and killed by Marshal Schiller. Dodge and Piper argue about their plan; Dodge reveals he needs to escape to collect $5 million he stole. Piper demands half in exchange for his help. Gibson begins to grow suspicious of the marshal's motives and circumstances when he finds out the company from which Dodge stole the money by hacking did not press charges; the company is owned by Matajano. Matajano commissions the hitman from the food delivery to recover a computer disc from, then kill, Dodge. Gibson reveals the magazine he found at the escape scene had blanks—the guards were never intended to kill anyone, and it was supposed to be a setup. Piper and Dodge are cornered by a hunter whom Piper attacks, causing him to have a heart attack. They take his car and drop his body at a hospital, then demand a woman named Cora (Salma Hayek) drive them to a hideout. At her house, they change clothes and part ways—Piper gives Dodge his harmonica for good luck. Dodge goes to a strip club to meet up with his girlfriend; after arranging to meet his hacking partner, Puffy, at a massage parlor to hand off the disc, Matajano's thugs enter their hotel room and kill her and begin to torture Dodge. Piper arrives and kills several of the hitmen, escaping with Dodge. He reveals that he's an undercover cop that Marshal Schiller hired to break Dodge out of prison so that he could recover the disc in exchange for exonerating him from an undercover drug bust that went bad in New York. The disc has evidence the attorney general needs against Matajano. At the massage parlor, Dodge meets up with Puffy, who is immediately shot by Matajano's men. Gibson, who hired a private investigator to get him information on Dodge, also arrives and participates in the gunfight. Piper and Dodge escape on special Ducati motorcycles left by Puffy; Gibson is reprimanded for not leaving the case to the attorney general. Not knowing the location of the disc, Piper and Dodge get desperate. Dodge notices a clue on his bike that lead them to the Georgia Dome and the disc, with Cora's help. The marshal (revealed to be working for Matajano to get the disc before the attorney general), Gibson, Dodge and Piper all end up in a gunfight. Piper and Dodge again escape with Cora's help, telling the attorney general they will hand off the disc at the top of Stone Mountain. Dodge and Piper lead Matajano's men on a chase up the mountain which results in Piper killing them; he meets up with Dodge and they ride a skycar up the mountain. The marshal, presumed dead in the gunfight, stops the car and demands the disc. Piper eventually throws him from the car and they hand the disc off to the attorney general, who exonerates them both and gets Piper his job back in New York.

After 32 people mysteriously drop dead in Boston, the U.S. government calls in scientists Dr. Joshua "Josh" Keyes and Dr. Serge Leveque. They determine that each person had a pacemaker and that electrical interference has caused them to malfunction. Other incidents involving the Earth's magnetic field lead Josh and Dr. Conrad Zimsky to the conclusion that the Earth's inner core has stopped rotating. Unless it is restarted, the magnetic field will continue to degrade and eventually collapse, exposing the Earth to devastating solar radiation. The U.S. government devises a plan to detonate nuclear weapons within the Earth's outer core to restart the rotation. They bring on Zimsky's former partner, Dr. Ed "Braz" Brazzelton, to build a vessel to deliver the bombs. The vessel, named Virgil, is made of unobtainium, a material that Braz developed to withstand extreme pressure. NASA pilots Commander Robert Iverson and Major Rebecca "Beck" Childs are enlisted to pilot Virgil and computer hacker Theodore Donald "Rat" Finch is recruited to avoid general panic by keeping news of further disasters and Virgil 's mission off the internet. Virgil is launched through the Marianas Trench and enters the crust using a laser-based drilling array. After entering the mantle, Virgil drills and falls into a gigantic empty geode, damaging the drilling array. While working to free the vessel from the outside, Iverson is killed by a falling shard. They escape before the geode is flooded with magma. As Virgil passes through a field of diamond formations, one of them breaches the compartment housing the weapons-control module. Serge sacrifices himself to get the team the information and tools they need to detonate the nukes before the compartment is sealed and jettisoned. The team reaches the outer core and realizes that it is much less dense than previously believed, meaning that their nuclear payload is too small for their current plan. Zimsky shares this with mission leader Lieutenant General Thomas Purcell and reveals to the team his work on DESTINI, a U.S. tectonic weapon that likely stopped the core's rotation. Purcell orders them to return, as he plans to try to use DESTINI to restart the core. However, Josh argues that doing so could permanently destabilize it and trigger massive natural disasters. The team elects to continue over Zimsky and Purcell's objections. A burst of ultraviolet rays destroys the Golden Gate Bridge and causes power outages along the West Coast. Concerned about further power outages preventing DESTINI from being fired, Purcell gives the order to do so. Josh communicates with Rat about DESTINI and the latter prevents Purcell from firing the weapon by redirecting power away from it. The team devises a plan to place a bomb in each of Virgil 's remaining compartments, jettison them, and stagger the detonations, using constructive wave interference to increase the force of the bombs. Braz sacrifices himself, going into the uncooled crawlspace of the ship and activating the control so they can manually detach compartments. As they set the charges, Josh and Zimsky realize that the last bomb needs more explosive power than the others. The bomb in the second-to-last compartment falls on Zimsky's leg and he is unable to escape before the compartment is ejected. Josh uses the nuclear fuel rods from Virgil 's reactor to provide the additional energy for the final detonation. The main compartment is left powerless as the bombs begin to detonate, killing Zimsky, and successfully restarting the core's rotation. Josh recalls that unobtainium can convert heat and pressure to energy and the two restore Virgil 's power in time to ride the pressure wave from the explosions out of the core. Eventually they breach the ocean floor near Hawaii, but lose power due to the cold water. Purcell and the U.S. Navy conducted search operations for them until Rat realized that the Virgil crew is using low-power ultrasound to draw whales to them, leading to Josh and Beck being rescued. Shortly afterward, Rat uploads information about Virgil, its team, and DESTINI to the internet, leading to worldwide news reports and tributes to the lost team members.

An iguana nest is exposed to the fallout of a military nuclear test in French Polynesia. Years later, a Japanese cannery vessel in the South Pacific is suddenly attacked by a giant creature, with only one fisherman surviving. While confined in a hospital in Tahiti, the traumatized survivor is visited by a mysterious Frenchman, who questions him over what he witnessed. The survivor repeatedly replies "Gojira". NRC scientist Dr. Niko "Nick" Tatopoulos is researching the effects of radiation on wildlife in the Chernobyl exclusion zone when he is interrupted by an official from the U.S. State Department who has come to pick him up for a special assignment. Nick is sent to Panama to observe a trail of destruction and footprints left by an unknown creature and then Jamaica to examine the damaged ship with massive claw marks on it. Nick identifies skin samples he discovered in the shipwreck as belonging to an unknown species. He dismisses the military's theory of the creature being a living dinosaur, instead deducing that it is a mutant created by nuclear testing in French Polynesia, close to where it was last spotted. The creature drowns several fishing trawlers in the Eastern American Seaboard, and travels to New York City, leaving a path of destruction. The U.S. military orders an evacuation of the city. On Nick's advice, a plan is set to lure the creature into revealing itself with a large pile of fish. However, their attempt to kill it fails, causing further damage to the city before it escapes. Nick collects a blood sample and, by performing a pregnancy test, discovers the creature reproduces asexually and is about to lay eggs. Nick also meets up with his ex-girlfriend Audrey Timmonds, a young aspiring news reporter. Unnoticed by Nick, she uncovers a classified tape in his provisional military tent concerning the monster's origins and turns it over to the media. She hopes to have her report put on TV to launch her career as a news reporter. Charles Caiman misuses the tape in his own report, declaring it his discovery, and dubs the creature " Godzilla ". As a result of the tape's disclosure, Nick is removed from the operation, and he ends his relationship with Audrey. His taxi is hijacked by the mysterious Frenchman, who identifies himself as Philippe Roaché, an agent of the French secret service. Philippe explains that he and his colleagues have been closely watching the events to cover up their country's role in the nuclear testing that created Godzilla. They suspect a nest somewhere in the city and cooperate with Nick to trace and destroy it. Godzilla resurfaces again and evades a second military strike. After diving into the Hudson River, it is attacked by Navy submarines. After destroying one submarine, it is shot down by torpedoes as it tries to burrow to safety; Godzilla sinks to the river bed and is believed to be dead by the authorities. Meanwhile, Nick and Philippe's team, followed by Audrey and her cameraman Victor "Animal" Palotti, find the nest inside Madison Square Garden. The eggs begin to hatch, and the offsprings attack the team as they carry the scent of fish. Nick, Animal, Audrey, and Philippe take refuge in the Garden's broadcast booth and successfully send a live news coverage to alert the military of the offsprings presence. A prompt response involving an airstrike is initiated as the four escape moments before the Air Force jets bomb the arena. Audrey and Nick reconcile before Godzilla emerges from the Garden's ruins, having survived the torpedo attack. Enraged by the deaths of its young, it chases them across the streets of Manhattan. The team manages to trap Godzilla within the suspension cables of the Brooklyn Bridge, allowing the returning Air Force to strike it down with missiles. Godzilla collapses to the ground and dies, as the remaining citizens and authorities celebrate. Audrey tells Caiman that she quits working for him after what he has done, before leaving with Nick and Animal. Philippe, taking Animal's tape and promising to return it after removing its specific contents, thanks Nick for his help, and parts ways. Meanwhile, in the ruins of Madison Square Garden, a single surviving egg hatches, and the hatchling roars to life.

In 1999, Parker Barnes is a former Los Angeles police officer imprisoned for killing political terrorist Matthew Grimes, who killed Parker's wife and daughter. Barnes killed Grimes but also accidentally shot two news reporters in the process and was sentenced to 17 years to life. Barnes and fellow convict John Donovan are testing a virtual reality system designed for training police officers. The two are tracking down a serial killer named SID 6.7 at a Japanese sushi restaurant in virtual reality. SID (short for Sadistic, Intelligent, Dangerous, a VR amalgam of the most violent serial killers throughout history) causes Donovan to go into shock, killing him. The director overseeing the project orders the programmer in charge of creating SID, Dr. Darrel Lindenmeyer, to shut down the project with Commissioner Elizabeth Deane and her associate, William Wallace, as his witnesses. Following a fight with another prisoner, Barnes meets with criminal psychologist Dr. Madison Carter. Meanwhile, Lindenmeyer informs SID that he is about to be shut down because Donovan's death was caused when SID disabled the fail-safes. At SID's suggestion, Lindenmeyer convinces another employee, Clyde Reilly, that a sexually-compliant virtual reality model, Sheila 3.2, another project created by Lindenmeyer, can be brought to life in a synthetically grown android body. However, Lindenmeyer replaces the Sheila 3.2 module with the SID 6.7 module. Now processed into the real world, SID 6.7 kills Reilly. Once word gets out of SID being in the real world, Deane and LAPD Chief William Cochran offer Barnes a deal: if he catches SID and brings him back to virtual reality, he will be pardoned. Barnes agrees, and with help from Carter they discover that Matthew Grimes, the terrorist who killed Barnes's wife and daughter, is a part of SID 6.7's personality profile. After killing a family along with a group of security guards, SID heads over to the Media Zone, a local nightclub, where he takes hostages. Barnes and Carter go to the nightclub to stop him, but SID escapes. The next day, SID begins a killing spree at the Los Angeles Olympic Auditorium where a UFC match is taking place. Barnes arrives at the Stadium to capture SID and finds him on a train, where another hostage is being held by SID. Barnes seemingly kills the hostage in front of horrified witnesses and is sent back to prison. Having caught up with Barnes after the incident, Carter tries to prove Barnes's innocence, but Barnes is freed from his prisoner transport by SID, who once again escapes. Wallace and Deane are about to have Barnes terminated via a fail-safe transmitter implanted in his body, but Cochran destroys the system after learning from Carter that Barnes didn't kill the hostage on the train. SID kidnaps Carter's daughter Karin and takes over a television studio. Lindenmeyer, having come out of hiding, sees what SID is doing and is impressed but is captured by Carter. After a fight on the roof of the studio, Barnes ultimately destroys SID's body but is unable to learn where he hid Karin. They place SID back in VR to trick the location out of him which proves to be one of the fan enclosures on the studio roof. When SID discovers that he is back in virtual reality, he goes into a rage. Cochran lets Carter out of VR, but Lindenmeyer kills Cochran before he can release Barnes. Barnes starts to go into the same shock that Donovan suffered, but Carter kills Lindenmeyer and saves Barnes. Barnes and Carter return to the building that SID took over in the real world and save Karin from a booby trap set up by SID that's similar to the one that killed Barnes' family. After Karin is saved, Barnes destroys the SID 6.7 module.

The crew of the newly commissioned USS Enterprise (NCC-1701-A) are enjoying shore leave after the starship's shakedown cruise, with Kirk, Spock, and McCoy camping at Yosemite National Park. Their leave is interrupted when the Enterprise is ordered by Starfleet Command to rescue a human, a Klingon, and a Romulan, all diplomats who have been taken hostage on Nimbus III, a planet set aside as a neutral location to advance dialogue among the Federation, Klingon Empire, and Romulan Star Empire. Learning of the Enterprise ' s mission, the ambitious Klingon Captain Klaa decides to pursue Kirk for personal glory. On Nimbus III, the Enterprise crew discovers that Sybok, a renegade Vulcan, is behind the hostage crisis, prompting Spock to admit that Sybok is his half-brother. After the Enterprise crew saves the hostages, Sybok reveals that the hostage-taking was a ruse to lure a starship, which he plans to use to travel to the mythical planet Sha Ka Ree. Sybok believes it lies behind the Great Barrier, a powerful energy field at the galaxy's center, and that God is located there. To take control of the ship, Sybok uses his ability to reveal and heal the innermost pain of a person through the Vulcan mind meld, thus gaining the loyalty of most of the crew. McCoy's pain is that he had helped fulfill his terminally ill father's request to die, only to find later that a cure could have saved his father's life, which has caused him years of guilt. Spock's pain is the knowledge that his father rejected him at birth for being "too human". Kirk refuses to let Sybok remove his pain, claiming that it is necessary to make him human. The Enterprise successfully breaches the Great Barrier, unaware they are being followed by Captain Klaa's warship, a Klingon bird-of-prey. They discover a lone barren planet, and Sybok, Kirk, Spock, and McCoy take a shuttlecraft down to the surface. It appears uninhabited, but after Sybok calls out, a glowing field appears which quickly morphs through many forms representing various religions before settling into the image of a bearded human face, to which Sybok explains that they have come for "your wisdom". The entity asks how they breached the barrier, and upon being told about the Enterprise, it declares that it will use the ship to carry its wisdom to every corner of the universe. A skeptical Kirk asks "What does God need with a starship?", and when the entity asks who he is, Kirk expresses doubt that the actual supreme being would not already know. Irritated, the entity attacks him and Spock, after which they discover it is a powerful and malicious being, imprisoned on Sha Ka Ree in the distant past, with the Great Barrier put in place to keep it from escaping. Realizing his earlier naiveté, Sybok apologizes and attempts to distract the entity by physically attacking it, allowing the others the opportunity to escape. Kirk orders the Enterprise to fire a photon torpedo at the entity, but only Sybok is killed by the strike. Spock and McCoy beam back to the ship moments before the Klingon ship unexpectedly attacks and damages the Enterprise, stranding Kirk on the planet with the weakened and enraged entity. As Kirk attempts to escape from the entity, the Klingon Bird of Prey arrives and destroys the entity with a volley of disruptor fire. Kirk is beamed aboard the Klingon ship, where Spock is unexpectedly waiting. As Spock explains, he convinced the Klingon General Korrd (one of Sybok's hostages who had become a loyal follower) to order Captain Klaa to stand down and apologize for his actions, which Klaa grudgingly does. After returning to Earth, Kirk, Spock, and McCoy resume their camping trip at Yosemite.

A woman named Jen Kornfeldt travels to Nice, France, with her parents after a break-up. She meets a man named Spencer Aimes and agrees to join him later for drinks. He sneaks aboard a boat, planting a bomb on a helicopter, then arrives for his date with Jen. When the helicopter takes off, Spencer triggers the bomb. After a night of drinking, Spencer reveals he is a professional assassin, unaware that Jen has fallen asleep. Despite his boss Holbrook's objections, Spencer quits contract killing and begins a relationship with Jen. He eventually asks her father Mr. Kornfeldt for his blessing to marry her. Three years later, Spencer and Jen have settled into married life. When she surprises him with tickets to Nice for his birthday, he is less than enthusiastic, which Jen's friends convince her is a sign he is bored with their relationship. Spencer receives a "romantic" postcard from Holbrook with an ultimatum to take another assignment. Trying to refuse the job over the phone, Spencer hangs up when Jen's father arrives, prompting suspicion; he also notices the postcard. Mr. Kornfeldt brings Spencer to a surprise birthday party, where the latter's distraction over the assignment strengthens Jen's doubts about his commitment. This is further fueled in the morning when he rushes Jen off on her business trip. Jen decides to return home and finds Spencer fighting off his best friend Henry, secretly a fellow assassin, who reveals a $20 million bounty has been placed on Spencer and that anyone in his life could be an assassin. A sniper opens fire on the house, and Spencer and Jen flee. They lead Henry on a car chase through the neighborhood and flip his car onto rebar, killing him. After the couple find Holbrook dead in his hotel room, Jen vomits and realizes she might be pregnant. At Spencer's office, she takes a pregnancy test, while he is attacked by his secretary, Vivian. But Spencer, with Jen's help, manages to kill her. Jen's test is positive, and despite Spencer's pleas, she drives off alone. Spencer is attacked by a delivery driver, who is run over and killed by one of Spencer's co-workers, Olivia. She then tries to run him over, but Jen returns and rams Olivia's car into a fuel tank, which Spencer shoots. The car explodes, killing Olivia in the process. Spencer and Jen discuss their future together and return home, evading next door neighbors Mac and Lily, who are also assassins. Making their way through the neighbourhood block party, they enter the house to retrieve Spencer's bug-out bag. Spencer subdues the neighbours, while Jen's best friend Kristen, yet another assassin, holds Jen's mother hostage in a Mexican standoff with Jen. Jen's father arrives and kills Kristen. In a standoff with Spencer, he reveals that he ordered the hit. Aware of Spencer's career all along, Mr. Kornfeldt explains that he was a former operative himself and had been Spencer's target in Nice; he embedded the assassins in Spencer and Jen's lives. The postcard from Holbrook led Mr. Kornfeldt to believe that Spencer had resumed his old job, so he activated the assassins. To prove he has truly left his old profession behind, Spencer drops his gun, assuring Mr. Kornfeldt he has no intention of killing him. Jen, now convinced, reveals her pregnancy to her parents. Her father, after killing one last assassin, drops his gun as well, and the family makes peace by building a trust circle. Months later, Spencer – growing a moustache to emulate Mr. Kornfeldt – and Jen leave her parents babysitting their baby boy, guarded by lasers.
