In 1935, American archeologist Indiana Jones survives a murder attempt in China from Shanghai Triad crime boss Lao Che, who hired him to retrieve the remains of Nurhaci. Jones flees from the city accompanied by his young orphan sidekick Short Round and nightclub singer Willie Scott, unaware that the plane they are traveling on is owned by Lao Che. The plane's pilots dump the fuel and parachute away, but Jones, Willie and Short Round escape using an inflatable raft before the plane crashes. The trio ride down the slopes of the Himalayas and fall into a river before arriving at the Indian village of Mayapore. There, the villagers plead for Jones' aid in retrieving a sacred lingam stone stolen along with the village's children by evil forces from the nearby Pankot Palace. Jones agrees to do so, hypothesizing that the stone is one of the five Sankara stones given by the Hindu gods to help humanity fight evil. Traveling to the palace, the trio are warmly welcomed and allowed to stay for the night as guests, attending a banquet hosted by the palace's young maharaja Zalim Singh. During the night, Jones is attacked by an assassin, but manages to kill him. He discovers a series of tunnels underneath the palace and explores them with Willie and Short Round. Finding a temple and a complex of mine tunnels, they observe Thuggee cultists conducting a human sacrifice. The cult, which possesses three Sankara stones, is revealed to have brainwashed Singh and abducted the children of Mayapore, using them as slave labor to find the remaining stones. During Jones' attempt to retrieve the stones, the trio is captured. Thuggee high priest Mola Ram forces Jones to drink a potion that places him into a trance-like state, under which he prepares Willie for sacrifice. Short Round is briefly enslaved in the tunnels, but he escapes and interrupts Willie's sacrifice by freeing Jones from his trance, who in turn rescues Willie. The trio defeat multiple cultists, collect the Sankara stones and free Singh and the children, escaping an attempt by Mola Ram to drown them. When he and his men ambush the trio on a rope bridge, Jones severs it with a sword, causing several cultists to fall into the crocodile-infested river far below. As Jones, Willie, Short Round, and Mola Ram struggle to climb up the broken bridge, Jones invokes the name of Shiva, triggering the stones to burn through his satchel. Two stones fall into the river; Mola Ram catches the third, but it burns his hand and he falls and is devoured by the crocodiles. Indy catches the stone with no ill effects and climbs up as a regiment of British Indian Army soldiers arrives, alerted by Singh, to defeat the remaining cultists. Jones, Willie, and Short Round return to Mayapore to hand over the stone, and Jones and Willie embrace as the villagers celebrate its and their children's return.

In 2200, Aline Ruby, a private detective, and Carlos Rivera, an android replica of her partner who died five years earlier, are sent to Earth to capture Roberta Williams, a robot-hacking criminal. Back on Mars, Roberta's arrest warrant has disappeared and she is released. A new investigation is entrusted to the duo: to track down Jun Chow, a cybernetics student known for illegally jailbreaking androids who, like her roommate, has gone missing. Aline and Carlos venture to the depths of Noctis, the main terrestrial establishment of Mars created thanks to the progress of robotics, and where humans and various forms of androids seem to coexist in harmony. The city turns out to hide secrets such as trafficking and clandestine computer labs. Meanwhile, activists try to free the robots from the security constraints that bind them to humans. Ultimately, the robots are successfully emancipated and revolt, but peacefully, by uploading their consciousnesses to computers aboard spaceships and thus escaping to space. Carlos, grief-stricken by the loss of his partner and realizing that he is a dead consciousness embodied in a machine who has been "trying to hold onto a life that's moved on without him", decides to go with the robots.

Triad boss Lung survives an assassination attempt in a restaurant in which one of his men is killed. The restaurant is owned by "Fat Cheung", an underboss of Lung's triad. To ensure his safety, Lung's right hand man and brother, Frank, has hired five bodyguards to stay close to their boss 24/7: Curtis, a retired veteran of the triad who was living a normal life as a hairdresser; James, a loner and the firearms expert of the five; Roy, a rising capo and his quick-witted underling Shin; and Mike, a former pimp and sharpshooter. An initial assassination attempt on Lung fails when a sniper attacks the cars with Lung and his bodyguards from the rooftop of a high-rise. Lung gets shot, but a bullet-proof vest prevents further damage. The men manage to fight off the attack and Curtis decides to leave in the cars with Lung, James, Mike and Shin even though Roy hasn't returned (he left the scene to pursue a second attacker). Roy returns angrily in a taxi to Lung's house and beats up Curtis (who doesn't oppose). The next day Curtis makes amends by killing a criminal who harassed Roy's night club. The five bodyguards are fighting off two additional assassination attempts and trail a surviving hitman to the hideout of the attackers. After a gunfight they manage to capture one of the assassins alive. It becomes evident that the hits were contracted by Fat Cheung and Lung sends his henchmen Frank to kill him. The bodyguards kill the captured hitman and the five men celebrate the end of their mission in a restaurant. Frank hands out five envelopes with the pay to Curtis and tells him that he learnt about an affair between Shin and the wife of Lung. He requests that Shin be executed and Curtis tells him that he'll handle it. Curtis drives to James, asks him for a gun and arranges a meeting with Shin in the evening. James warns Roy and since he's responsible for Shin as his boss, he confronts him with the allegation. Shin confesses having been seduced by Mrs. Lung. Roy tells Curtis that he can't allow for Shin to be killed. They form the plan to have Shin escape in a boat to Taiwan but eventually discard the plan since Frank would then pursue Roy and the rest of them for failing instead. In the evening the five men meet in an otherwise empty restaurant to sort out the situation. James leaves to ask Lung for clemency and to spare Shin's life. When he arrives at Lung's house he witnesses a henchmen of Lung killing the unfaithful Mrs. Lung. James realizes the hopelessness of his attempt and returns to the restaurant where it comes to a Mexican standoff between the men. Curtis shoots Shin, while Roy empties his magazine without aiming at Curtis. When the men leave the restaurant, Curtis throws a blank towards James, thus revealing that the death of Shin (who escapes through the backdoor) was staged for Lung.

In April 1805, during the Napoleonic Wars, the British frigate HMS Surprise is ambushed by the French privateer Acheron off Brazil, suffering heavy damage by cannon balls. After escaping by using rowboats to tow the ship into a nearby fog bank, Surprise ' s captain Jack Aubrey refuses to return home and insists on giving pursuit at any cost. Shortly afterwards, Surprise is again chased by Acheron by using a weather helm wind advantage; that night, Aubrey deploys a crude, lantern-lit decoy raft, sails a different course, and sends the Acheron going the wrong direction. Now in pursuit of the Acheron, the French ship attempts to lose them in a heavy storm at Cape Horn. Surprise nearly sinks, and Aubrey sacrifices popular crewmember Warley to save the ship as a whole. Escaping calamity, but losing the Acheron, Aubrey follows a hunch and changes course for the Galápagos Islands, where he suspects the enemy ship will be hunting British whalers. To make up for the mounting losses, Aubrey promises Surprise ' s surgeon and his close friend, Stephen Maturin, that he will become the first naturalist to explore the islands' unique flora and fauna. However, Surprise then hits the doldrums, becoming stuck with no wind. Drifting for days in the heat, the crew becomes restless and superstitious, and blame midshipman Hollom for their misfortunes; the men believe him to be a cursed "Jonah", and begin treating him poorly. Guilt-stricken, Hollom commits suicide in the night by jumping overboard with a cannonball. Mystically, the wind picks up the next morning, and Surprise resumes the chase. Arriving at the Galápagos Islands, the men are amazed by the wildlife. However, they quickly encounter marooned whalers who confirm Aubrey's suspicions; they were raided by the Acheron. Aubrey breaks his promise to Maturin and pursues the ship. As they depart, the captain of marines accidentally shoots Maturin in the abdomen while carelessly aiming at an albatross. Remorseful, Aubrey turns around, anchors at the Galápagos, and assists Maturin in performing self-surgery. Finally giving up his pursuit of Acheron, Aubrey grants Maturin the freedom to explore the Galápagos and gather specimens before they return to Portsmouth. While looking for the flightless cormorant, Maturin discovers Acheron anchored on the other side of the islands. He hurriedly returns to Surprise and informs Aubrey. Back onboard the ship, Maturin shows Aubrey a curious camouflaging phasmid disguised as a stick. Inspired, Aubrey orders his warship to become disguised as a vulnerable, unarmed whaler. The crew don disguises, paint over the ship's name, and plot an ambush. Acheron is successfully tricked, and is lured into an up-close raid. The Surprise reveals her flags, and dismasts the privateer with sudden cannon fire. Aubrey leads a boarding party onto the stalled Acheron and captures the ship after fierce hand-to-hand combat, with significant losses on both sides. Searching for the enemy captain, Aubrey finds the Acheron ' s surgeon, de Vigny, who informs him that his French counterpart has died; his last request was to give Aubrey his sword. Both ships are repaired to seaworthy condition by the crew of Surprise, whose first lieutenant Pullings is promoted to captain and ordered to sail Acheron to Valparaíso to parole their French captives. As Acheron sails away, Maturin mentions to Aubrey that de Vigny died from a fever months ago. Realizing that the "surgeon" was really the Acheron 's captain in one final ruse, Aubrey orders the crew of Surprise to reverse course and to beat to quarters in pursuit of the captured ship. Maturin is once again denied the chance to explore the Galápagos, but Aubrey wryly notes that since the bird he seeks is flightless, "it's not going anywhere." As is their recreational entertainment on the voyage, the officer duo joyfully plays their violin and cello in the Captain's cabin to Musica notturna delle strade di Madrid as Surprise pursues the captured Acheron once more.

U.S. Army pilot Captain Colter Stevens wakes up on a Metra commuter train going into Chicago. He is disoriented, as his last memory was of flying a mission in Afghanistan. However, to the world around him – including his friend Christina Warren and his reflection in the train's windows and mirrors – he appears to be a different man: a school teacher named Sean Fentress. As he expresses his confusion to Christina, the train explodes while passing another train, killing everyone aboard. Stevens abruptly awakens in a dimly lit cockpit. Communicating through a video screen, Air Force Captain Colleen Goodwin verifies Stevens' identity and tells him of his mission to find the train bomber before sending him back to the moment he awoke on the train. Believing he is being tested in a simulation, Stevens finds the bomb in a vent inside the lavatory but is unable to identify the bomber. Still thinking he is in a simulation, Stevens leaves the bomb and goes back down to the main cabin before the train explodes again. Stevens again reawakens in his capsule and after demanding to be briefed, learns that the train explosion actually happened and that it was merely the first attack of a suspected series. He is sent back yet again, eight minutes before the explosion, to identify the bomber. This time, he disembarks from the train (with Christina) to follow a suspect. This turns out to be a dead end, the train still explodes in the distance, and Stevens is killed by a passing train after falling onto the tracks while interrogating the suspect. The capsule power supply malfunctions as Stevens reawakens. He claims to have saved Christina, but Dr. Rutledge, head of the project, tells him that she was saved only inside the "Source Code". Rutledge explains that the Source Code is an experimental machine that reconstructs the past using the dead passengers' residual collective memories of eight minutes before their deaths. Therefore, the only thing that matters is finding the bomber to prevent the upcoming second attack in Chicago. On the next run, Stevens learns that he was reported as killed in action two months earlier. He confronts Goodwin, who reveals that he is missing most of his body, is on life support, and is hooked up to neural sensors. The capsule and his healthy body are "manifestations" made by his mind to make sense of the environment. Stevens is angry at this forced imprisonment. Rutledge offers to terminate him after the mission, and Stevens eventually accepts. After numerous attempts, including being arrested by train security for trying to obtain a weapon, Stevens identifies the bomber through a fallen wallet as the nihilistic domestic terrorist Derek Frost. He memorizes Frost's license and vehicle registration plates, and discovers a dirty bomb built inside a van owned by Frost; Christina follows him, and Frost shoots both of them dead. Outside the Source Code, Stevens relays his knowledge to Goodwin, which helps the police arrest Frost and prevents the second attack. He is congratulated for completing his mission. Rutledge secretly reneges on his deal to let Stevens die, as he is still the only candidate able to enter the Source Code. Being more sympathetic to his plight, Goodwin sends Stevens back one last time and promises to disconnect his life support after eight minutes. This time, he sets a date with Christina, defuses the bomb, apprehends Frost, and reports him to the police. He calls his father under the guise of a fellow soldier and reconciles with him, and sends Goodwin an email. After eight minutes, Goodwin terminates Stevens's life support. As the world around him continues to progress beyond eight minutes, Stevens confirms his suspicion that the Source Code is not merely a simulation, but rather a machine that allows the creation of alternate timelines. He and Christina leave the train and go on a date. In the same (alternate) reality, Goodwin receives Stevens's message. He tells her of the Source Code's true capability and asks her to help the alternate-reality version of him.

On Devil's Night in crime-ravaged, decrepit Detroit, a young woman, Shelly Webster, is raped and mortally wounded, while her rock musician fiancé, Eric Draven, is shot and thrown to his death from the window of their loft apartment. Police Sergeant Daryl Albrecht accompanies Shelly to the hospital, where she eventually dies from her injuries. A narration recounts the legend of a crow that carries souls to the land of the dead; if a person dies under tragic circumstances, the crow can resurrect their restless spirit to set things right. One year later, Shelly and Eric's graves are visited by Sarah, a young girl the pair cared for due to her neglectful mother. A crow lands on Eric's gravestone and taps on it, resurrecting him. Disoriented and distressed, Eric returns to their ruined loft and experiences flashbacks of the murders: a gang of men—Tin Tin, Funboy, T-Bird, and Skank—attacked the couple because they were protesting forced evictions in their apartment building, which the gang’s leader, the ruthless crime boss Top Dollar, intended to seize. Realizing that any injury he suffers heals instantly, Eric dons black-and-white face paint and sets out to avenge himself and Shelly, guided by the crow. The crow leads Eric to Tin Tin, whom he stabs to death. He next visits the pawn shop where Tin Tin had pawned Shelly's engagement ring. Eric recovers the ring and blows up the shop but spares the owner, Gideon, so he can alert Top Dollar's men that Eric is coming for them, only for Top Dollar to kill Gideon. Albrecht begins investigating the apparent vigilante disturbances, while Eric finds Funboy taking drugs with Sarah's estranged, addicted mother, Darla. He gives Funboy a fatal overdose and purges the drugs from Darla's body, telling her that Sarah needs her. Eric visits Albrecht and confirms his suspicions about the vigilante's identity. Albrecht tells Eric that he stayed with Shelly until she died, witnessing the thirty hours of suffering she endured. Eric touches Albrecht, absorbing the pain Shelly felt. Later, Eric saves Sarah from being hit by a car, revealing to her that he has returned. Eric next targets T-Bird, killing him in an explosion. The following morning, Sarah and Darla reconcile, and Sarah reunites with Eric at his apartment. Top Dollar holds a meeting with his associates to discuss plans to burn the city to the ground on Devil's Night. Eric arrives for Skank, but a gunfight erupts, ending with Eric throwing Skank from a window to his death. Top Dollar, his lover and half-sister Myca, and his right-hand man Grange escape. Myca deduces that the crow is the source of Eric's immortality. Satisfied with his vengeance, Eric gives Shelly's engagement ring to Sarah and returns to his grave. Grange abducts Sarah on her way home and takes her to an abandoned church, where Myca and Top Dollar await. Top Dollar takes Shelly's ring. The crow alerts Eric to Sarah's plight, and he rushes to rescue her but is ambushed by Grange, who wounds the crow and renders Eric vulnerable. Albrecht arrives and kills Grange, while Myca attempts to seize the crow for its power; it claws out her eyes, causing her to fall to her death from the bell tower. Top Dollar retreats to the church roof with Sarah, where he fights and badly wounds Eric, and reveals that he ordered T-Bird and his men to clear their apartment, making him responsible for Eric and Shelley's murder. Eric transfers Shelly's pain into Top Dollar, causing him to stumble off the roof and be fatally impaled on a gargoyle. Sarah and a wounded Albrecht are recovered from the church, while a dying Eric goes to Shelly's grave, where her spirit arrives to comfort him and return his body to rest. Some time later, Sarah visits the graves, and the crow gives her Shelly's ring.

In Toronto, Scott Pilgrim, a 22-year-old bassist for unsuccessful indie garage band Sex Bob-Omb, dates Knives Chau, a 17-year-old high-school student, to the disapproval of his friends in the band, his younger sister Stacey, and his roommate Wallace Wells. Scott meets Ramona Flowers, an American Amazon delivery girl, at Julie Powers’ party, after having first seen her in a dream. Scott loses interest in Knives but does not break up with her immediately before pursuing Ramona. When Sex Bob-Omb plays in a battle of the bands sponsored by record executive Gideon Graves, Scott is attacked by Ramona's ex-boyfriend Matthew Patel. Sex Bob-Omb's competition is incinerated by Matthew's fireball attacks, but Scott defeats him and learns he must defeat her remaining six evil exes in order to date Ramona. Scott finally breaks up with Knives, who blames Ramona and swears to win him back by becoming more like Ramona. Scott soon encounters Ramona's second ex, actor and skateboard junkie Lucas Lee. Scott defeats Lucas by tricking him into attempting a grind on a 200-plus step icy railing and crashing explosively. The band is soon asked to open for Clash at Demonhead, whereupon Scott encounters Ramona's third ex, the super-powered vegan bassist Todd Ingram, who is dating Scott's ex, Envy Adams, the lead singer. Scott deceives Todd into drinking half and half, and Todd is confronted by the vegan police and stripped of his powers; Scott then delivers the final blow. Scott then encounters Ramona's fourth ex, bisexual ninja Roxy Richter, and with the help of Ramona, he manages to beat her. Scott's growing frustration soon boils over, and after an outburst regarding Ramona's dating history, she breaks up with him while leaving him a list of her exes. At the next battle of the bands, Sex Bob-Omb defeats Ramona's fifth and sixth exes, techno twins Kyle and Ken Katayanagi, earning Scott an extra life. Despite this, Ramona appears to get back with her seventh and final ex, Gideon. Sex Bob-Omb accepts Gideon's record deal, except Scott, who quits the band in protest, during which their roadie, Young Neil, becomes their new bassist. Gideon invites Scott to his venue, the Chaos Theater, where Sex Bob-Omb is playing. Resolving to win Ramona back, Scott challenges Gideon to a fight for her affection, earning the "Power of Love" sword. Knives interrupts the battle, attacking Ramona, and Scott is forced to reveal that he cheated on both of them. Gideon kills Scott, and Ramona visits him in limbo to reveal that Gideon has implanted her with a mind control device. Scott uses his 1-up to come back to life and re-enters the Chaos Theater. He makes peace with his friends and challenges Gideon, this time for himself, gaining the "Power of Self-Respect" sword. After apologizing to Ramona and Knives for cheating on them and accepting his own faults, Scott joins forces with Knives and they defeat Gideon. Now free from Gideon's control, Ramona prepares to leave. After the fight, Scott is faced by his darker version, Nega-Scott, with whom he hits it off. Knives accepts that her relationship with Scott is over and, at her encouragement, he leaves with Ramona to "try again".

Vassili Zaitsev, a replacement soldier of the Red Army, arrives east of the River Volga during the Battle of Stalingrad in 1942. After a dangerous trip across the river into the city, he is forced to join a human wave attack carrying only rifle cartridges. He takes cover during the chaotic battle with Commissar Danilov. With one rifle, Vassili kills five German soldiers before they escape. Red Army commander Nikita Khrushchev asks his subordinates how to improve morale. Danilov recommends inspiring hope rather than punishing in fear and suggests that they revive the army newspaper and publishes heroic tales of Vassili's exploits. Vassili is transferred to the sniper division and becomes friends with Danilov. Both also become romantically interested in Tania Chernova, a private in the local militia. In fear for her safety, Danilov has her transferred to an intelligence unit, ostensibly to make use of her German skills in translating radio intercepts. With Soviet snipers taking an increasing toll on the Germans, Major Erwin König is deployed to kill Vassili and crush Soviet morale. When the Red Army command learns of König's mission after he wipes out Vassili's sniper unit, they dispatch König's former student Koulikov to help Vassili kill him. König, however, outmaneuvers Koulikov and kills him, shaking Vassili's spirits. Danilov finds a boy, Sacha Filipov, who volunteers to act as a double agent by passing König false information about Vassili's whereabouts in exchange for food. Vassili sets a trap for König and manages to wound him with the help of Tania. During a second attempt, Vassili falls asleep, and his sniper log is stolen by a looting German soldier. The German command takes the log as evidence of Vassili's death and plans to send König home, but König does not believe that Vassili is dead. General Friedrich Paulus confiscates König's dog tags to prevent Soviet propaganda from profiting if König is killed and identified. In turn, König gives the general a War Merit Cross that was posthumously awarded to his son, a lieutenant in the 116th Infantry Division who was killed in the early days of the battle. König tells Sacha where he will be next after deducing that the boy is responsible for his being wounded. Tania and Vassili have meanwhile fallen in love. That night, Tania secretly goes to the Soviet barracks and makes love with Vassili. The jealous Danilov disparages Vassili in a letter to his superiors. König spots Tania and Vassili waiting for him at his next ambush spot, confirming his suspicions about Sacha. He then kills the boy and hangs his body to bait Vassili. Vassili vows to kill König and asks Tania and Danilov to evacuate Sacha's mother. Tania is wounded by shrapnel en route to the boats. Thinking she is dead, Danilov regrets his jealousy of Vassili and even his ardor for communist ideals begins to falter. Finding Vassili waiting to ambush König, Danilov removes his helmet and exposes himself to provoke König into shooting him and revealing his own position. Thinking that he has killed Vassili, König goes to inspect the body only to find himself in Vassili's rifle sights. Accepting his fate and removing his cap, König grimly turns to look Vassili in the face before being shot in the head. Two months later, after Stalingrad has been liberated and German forces have surrendered, Vassili finds Tania alive and recovering in a field hospital.

Cyrus, charismatic leader of the Gramercy Riffs, the most powerful gang in New York City, requests that 100 of the city's gangs each send nine unarmed delegates to Van Cortlandt Park for a midnight summit. The Warriors, a gang from Coney Island, send a delegation consisting of "warlord" (leader) Cleon; "war chief" (second-in-command) Swan; enforcer Ajax; scout Fox; graffiti artist Rembrandt; music-man Snow; bearer Vermin and soldiers Cowboy and Cochise. Cyrus proposes a citywide truce and alliance to the assembled crowd, allowing the gangs to control the city together since they collectively outnumber the police by three to one. Most of the gang members applaud this idea, but Luther, the unbalanced and sadistic leader of the Rogues, shoots Cyrus dead as the NYPD arrive to raid the summit. In the chaos, Luther realizes that Fox witnessed his actions; after failing to shoot him, he falsely accuses the Warriors of responsibility. Cleon denies the assassination, however he is viciously attacked by the vengeful Riffs, killing him. Meanwhile, the other Warriors escape to Woodlawn Cemetery, unaware that they have been implicated in Cyrus's killing. Masai, Cyrus's second-in-command in the Riffs, puts out a "dead or alive" bounty on the Warriors through a radio DJ. To Ajax's disappointment, Swan takes charge of the group as they try to get home. The Turnbull ACs spot the Warriors and try to run them down with a modified school bus, but they escape and board the MTA New York City Subway. On the ride to Coney Island, the train is stopped by a building fire alongside the tracks, stranding the Warriors in Tremont. Setting out on foot, they encounter the Orphans, who are insecure about their lowly status as they were excluded from Cyrus's meeting. After Mercy, the girlfriend of the Orphans' leader, instigates a confrontation, Swan throws a Molotov cocktail, and the Warriors run to the nearest subway station. Impressed and desperate to escape her depressing neighborhood, Mercy follows the Warriors. When the group arrives at the 96th Street and Broadway station in Manhattan, they are pursued by police and separated. Vermin, Cochise, and Rembrandt escape by boarding a subway car. Fox, struggling with a police officer, is thrown onto the tracks and killed by a passing train as Mercy flees the scene. The Baseball Furies chase Swan, Ajax, Snow, and Cowboy into Riverside Park, but they are defeated in a brawl. After the fight, Ajax sees a lone woman sitting on a park bench and leaves the group despite Swan's objections. When Ajax becomes sexually aggressive, the woman reveals herself as an undercover police officer and arrests him with the help of uniformed officers. Upon arriving at Union Square station, Vermin, Cochise, and Rembrandt are seduced by an all-female gang called the Lizzies and invited into their hideout. They narrowly escape the Lizzies' subsequent attack, learning in the process that the gangland community and the police believe the Warriors murdered Cyrus. As a lone scout, Swan returns to the 96th Street station, where Mercy joins him (although he spurns her advances). After reaching the Union Square station by walking along the tracks, they reunite with the remaining Warriors and fight with an overalls -wearing roller skating gang, the Punks, which allows Mercy to prove herself in combat. Meanwhile, an unidentified gang member visits the Riffs and tells them that he saw Luther shoot Cyrus. At dawn, the Warriors finally reach Coney Island, only to find Luther and the Rogues waiting for them. Swan asks Luther why he killed Cyrus, to which Luther replies, "No reason... I just like doing things like that!" Swan challenges Luther to single combat, but Luther pulls a gun instead. Swan dodges his shot and throws a switchblade into Luther's forearm, disarming him. The Riffs arrive, acknowledging the Warriors' innocence of Cyrus' murder while saluting their courage and skill. The Riffs let the Warriors leave before descending on the Rogues and Luther, who screams in anguish at his imminent demise. The radio DJ announces that the bounty on the Warriors has been cancelled and salutes them with a song, " In the City." The film ends with Swan, Mercy, and the rest of the gang walking down a Coney Island beach illuminated by the rising sun.

In September 1940, following a severe trade embargo imposed on a belligerent Japan by the United States a year prior, influential Japanese army figures and politicians push through an alliance with Germany and Italy, despite opposition from the Japanese navy, and prepare for war. The newly appointed Commander-in-Chief of the Combined Fleet, Admiral Isoroku Yamamoto, reluctantly plans a pre-emptive strike, believing Japan's best hope of controlling the Pacific Ocean is to quickly annihilate the American Pacific fleet anchored at Pearl Harbor. Air Staff Officer Minoru Genda is chosen to mastermind the operation, while his old Naval Academy classmate Mitsuo Fuchida is selected to lead the attack. In Washington, U.S. military intelligence has broken the Japanese Purple Code, allowing them to intercept secret Japanese radio transmissions indicating increased Japanese naval activity. U.S. Army Colonel Rufus S. Bratton and U.S. Navy Lieutenant Commander Alwin Kramer monitor the transmissions. At Pearl Harbor, Admiral Husband E. Kimmel increases defensive naval and air patrols around Hawaii. General Walter Short orders aircraft concentrated on the airfield runways to avoid sabotage by enemy agents, while some planes are dispersed to other airfields on Oahu. Diplomatic tensions escalate as the Japanese ambassador to Washington continues negotiations to stall for time. Bratton and Kramer learn from intercepted radio messages that the Japanese planned to send 14 messages from Tokyo to their embassy in Washington, with orders to destroy their code machines after receiving the final message. Deducing that the Japanese will launch a surprise attack after the messages are delivered, Bratton tries to warn his superiors. However, Chief of Naval Operations Harold R. Stark is indecisive over notifying Hawaii without first alerting President Franklin D. Roosevelt. In contrast, Army Chief of Staff General George Marshall 's order to alert Pearl Harbor of an attack is stymied by poor atmospheric conditions that prevent radio transmission and by a warning telegram not marked urgent. The Japanese fleet launches its aircraft at dawn on December 7, 1941. Two radar operators detect their approach to Hawaii, but the duty officer, Lieutenant Kermit Tyler, dismisses their concerns. Similarly, the claim by the destroyer USS Ward to have sunk a Japanese miniature submarine off the entrance to Pearl Harbor is dismissed as unimportant. The Japanese achieve total surprise, which Commander Fuchida indicates with the code signal "Tora! Tora! Tora!" The damage to the naval base is catastrophic, and casualties are severe. Several battleships are either sunk or heavily damaged; General Short's anti-sabotage precautions allow Japanese aircraft to easily destroy American planes on the ground. In Washington, a stunned Secretary of State Cordell Hull is asked to receive the Japanese ambassador Kichisaburō Nomura. The 14-part message – including a declaration that peace negotiations were at an end – was meant to be forwarded to the Americans thirty minutes before the attack, but the Japanese embassy failed to decode and transcribe it in time. The attack started while the two nations were technically still at peace. The distraught Nomura, helpless to explain the late ultimatum and unaware of the ongoing attack, is rebuffed by Hull. The Japanese fleet commander, Vice-Admiral Chūichi Nagumo, refuses to launch a scheduled third wave of attack aircraft for fear of exposing his fleet to U.S. submarines. General Short and Admiral Kimmel finally receive Marshall's telegram warning of impending danger hours after the attack is over. Aboard his flagship, Admiral Yamamoto informs his staff that their primary target – the American aircraft carriers – were not at Pearl Harbor, having departed days previously. Lamenting that the declaration of war arrived after the attack began, Yamamoto notes that nothing would infuriate the U.S. more and concludes: "I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve."

In 2046, Grey Trace, an auto mechanic, lives with his wife Asha who works for Cobalt, one of the companies contributing to human-computer augmentations. Grey asks Asha to help him return a refurbished car to his client Eron Keen, a renowned tech innovator. While visiting his home, Eron reveals his latest creation, a chip called STEM that can manage a human’s motor functions. Returning home, Grey and Asha's self-driving car malfunctions and crashes. Four men kill Asha and shoot Grey in the neck, severing his spinal cord. Grey returns home months later as a wheelchair-using quadriplegic, under the care of his mother, Pamela. Asha's death and the inability of Det. Cortez to identify their attackers causes Grey to sink into depression. After a suicide attempt, he is visited by Eron, who convinces him to accept a STEM implant. Grey regains control of his limbs and Eron has Grey sign a non-disclosure agreement, requiring Grey to pretend to still be paralyzed. While looking through a drone video feed of his wife's murder, Grey hears STEM speak in his mind. STEM says it can help Grey get revenge and quickly identifies one of the assailants, Serk Brantner, from the video. Grey breaks into Serk's home and finds proof Serk was "upgraded" through a secret military experiment, also connecting Serk to a local bar called the Old Bones. Serk arrives and attacks Grey, but STEM convinces Grey to temporarily give up control of his body, allowing STEM to turn Grey into a lethally efficient fighting machine, killing Serk with little effort. Cortez later sees drone footage of Grey’s wheelchair approaching Serk’s house, but his perceived paralysis negates him as a suspect. Eron has tracked STEM's movements and berates Grey for his vigilantism. Grey reveals STEM is speaking to him, which surprises Eron, who demands that Grey stop his investigation. Grey proceeds to the Old Bones and finds Tolan, another of the assailants. Grey allows STEM to torture Tolan to death, first getting the name of the assailants' ringleader, Fisk. Leaving the bar, Grey stumbles, and STEM informs him that Eron is attempting to shut them down remotely. STEM directs Grey to a nearby hacker, Jamie, who manages to remove STEM's input guard, then leaves just as Fisk arrives. Grey, with STEM's control restored, kills Fisk's companion. Grey returns home only for Pamela to see him walking, forcing him to reveal STEM's existence. Cortez arrives to interrogate them after finding Grey's wheelchair suspiciously abandoned at the Old Bones; she leaves after planting a listening device on Grey's jacket. Grey wishes to give up the hunt, but STEM explains that Fisk will track them down and kill them. STEM reveals that the hack gives it free control of Grey’s body. STEM uses Grey to drive to Fisk, causing an automated car to malfunction and crash into Cortez, who is tailing them. Cortez returns to Grey's home, where Pamela explains STEM. Grey and STEM find Fisk, who reveals he was only hired to paralyze Grey so he could be implanted. Fisk's own upgrades outpace Grey's movements. Grey taunts Fisk with the death of Serk, his brother, allowing STEM to gain the upper hand and kill Fisk. Fisk's phone reveals messages from Eron, suggesting he orchestrated all the events. Grey storms Eron's home, killing all personnel in his path, but is held at gunpoint by Cortez before he can kill Eron. Eron confesses how STEM forced him to do its bidding, having long since come to dominate all aspects of Eron's life in pursuit of its goal to become human. STEM kills Eron and attempts to kill Cortez, but Grey fights for control over his own body, managing to stab himself in the hand. Grey wakes up in a hospital room, not paralyzed. Asha explains he has been unconscious for two days following their crash. In reality, Grey is still in Eron's home. STEM, in full control, explains to Cortez that the psychological strain has finally broken Grey's mind; this was STEM's objective all along, as this allowed STEM to assume control over Grey's mind and body. Grey's consciousness believes the idyllic dream state it has found, while STEM kills Cortez and leaves.
