Through her friend Annie, call center intern Mae Holland secures a customer support position at The Circle, a tech and social media company. Mae takes the job, hoping to support her parents, particularly her father who suffers from multiple sclerosis, while her longtime friend Mercer is less supportive. At a company meeting, CEO Eamon Bailey introduces SeeChange, which uses small cameras placed anywhere to provide real-time high-quality video. Mae rises in The Circle, embracing social networking and meeting Ty Lafitte, who displays suspicion of other, more enthusiastic employees. At an outdoor company rally emphasizing the need for accountability in politics, The Circle's Chief Operating Officer, Tom Stenton, introduces Congresswoman Olivia Santos, who has agreed to open her daily workings to the public through SeeChange. Ty subsequently shows Mae the area containing the cloud server where all information collected by SeeChange is to be stored. Ty is the creator of TrueYou, the Circle's social network. Ty says that TrueYou has grown out of his control, and its current utilization is not what he intended. Later, Mae's mother shows Mae a picture of a chandelier Mercer made from deer antlers. She photographs it and shares it on her Circle profile. The image attracts negative attention to Mercer, with people accusing him of killing the deer. Mercer confronts Mae at work and tells her to leave him alone. Distressed, Mae goes kayaking at night and the rough waters cause her kayak to capsize, requiring rescue by the Coast Guard, who were alerted to the emergency through SeeChange cameras, which recorded her acquiring the kayak and capsizing it. At the next meeting, Eamon introduces Mae to the crowd and they discuss her experience of the rescue, which moves her to become the first "Circler" to go "completely transparent," which involves wearing a small camera and exposing her life to the world twenty-four hours a day. This damages her relationships with her parents and Annie, as Mae accidentally exposes private aspects of their lives, and they distance themselves from her as a result. At a board meeting, Eamon announces support from almost all fifty states for voting through Circle accounts. Mae takes it a step further, and suggests requiring every voting citizen to have a Circle account in order to do so. Eamon and Tom approve, but the suggestion upsets Annie. At the next company-wide meeting, Mae says that The Circle believes it can find anyone on the planet in under twenty minutes and introduces a program to find wanted felons. The program identifies an escaped child murderer within ten minutes, which prompts the Circlers in the audience to erupt in applause. Mae uses this successful test to suggest transparency can be a force for good. Mae says that the program can find anyone, and someone suggests Mercer. Mae is initially hesitant to use the program to locate Mercer, but Eamon persuades her to continue. Mercer is located in an isolated cabin. Startled by Circle users descending upon his home, he flees in a car, though a Circle user places a small camera on his car window without his knowledge. They pursue him via automobile and a flying drone, which causes Mercer to swerve uncontrollably off a bridge and die. Days later, Mae calls Annie, who has left The Circle and returned to Scotland, which has improved her well-being. Mae, however, finds that connection with others helps her cope with Mercer's death. Mae returns to The Circle, despite her parents' pleas. Mae calls Ty to ask for a favor and Ty reveals something that he has discovered. At the next company-wide meeting, Mae explains how connection has helped her recover. She speaks with Eamon, and invites Tom onstage, then invites Eamon and Tom to go fully transparent. She explains that Ty has found all their email accounts and exposed them to the world, as no one should be exempt. Eamon and Tom, upset, try to save face before Tom leaves the stage. Her superiors cut power to her presentation, and the stage goes dark, but the audience activates their mobile devices, illuminating Mae, who reiterates her advocacy of transparency. She later returns to kayaking, untroubled by the drones that shadow her.

A satellite, just launched from a Space Shuttle orbiter, collides with an unidentified object, which, after being spotted on radar moving at great speeds, had positioned itself just over the ship. The collision kills an astronaut in the launch bay. The events are witnessed by Bancroft and Price, the astronauts aboard. After returning to Earth, they are stonewalled when they try to discuss what happened. Harry Forbes, deputy director of NASA, simply tells them that "everything is going to be all right". After it makes a controlled landing in the Arizona desert, the damaged alien spacecraft is taken to Wolf Air Force Base in Texas and installed in Hangar 18, where scientists and other technicians, headed by Harry Forbes, can study it. Due to an impending presidential election, government officials are anxious to prevent any public knowledge of the event. Meanwhile, unbeknownst to Forbes, the Air Force puts out a news story blaming Bancroft and Price for the death of their colleague and for the destruction of the satellite. The men know that they can prove their innocence by viewing the telemetry tapes which recorded the UFO; but when they view them, all evidence of the object has been erased. Through a friend who works at a remote tracking station, they see the real telemetry and discover where the alien craft landed. They set out to expose the cover-up and clear their names. In the hangar, investigators enter the ship and find its two crew members dead. They determine that, during the collision with the satellite, chemicals were released in the craft that produced a short-lived toxic gas. They find a human woman in a stasis chamber, who later wakes up, screaming. They realize that symbols on the control panels match those used by ancient Earth civilizations. Video on the ship's computer shows extensive surveillance of power plants, military bases, industrial plants and major cities worldwide. Autopsies performed on the aliens show that they and humans had similar evolutionary processes. A scientist deduces that the ship could not have reached Earth on its own, but must have been launched from a much larger, faster and more long-ranged mother ship. In their pursuit of the truth, Bancroft and Price get closer to Hangar 18 but are targets of government agents. They elude one team, who are killed during a high-speed chase. Later, they find that the brakes on their rental car have stopped working, and after careening along roads, they come to rest on the grounds of a gas refinery. Agents begin shooting at them, so they drive off in an oil tanker. With the agents in pursuit, Price climbs onto the tanker, lets some gas out of the truck, lights an emergency flare, and tosses it. Their pursuers crash and are killed, but Price is fatally shot. When Forbes learns of Price's death, he demands the Air Force to take Bancroft to Hangar 18, or he will go to the press with the truth. Their cover-up and careers now threatened, government officials decide to remotely fly an explosives-filled plane into Hangar 18 to destroy all evidence of the event. The researchers have determined that the aliens have been to Earth before and that human beings are, in fact, their descendants. Further examination of the video footage reveals that the industrial and military sites are "designated landing areas", suggesting that the aliens are preparing to return. When Bancroft arrives at the base, he crashes through the base's security gate and, hiding in a warehouse, is discovered by Forbes, who takes him to Hangar 18 and the alien craft. Just as a researcher reveals that a translation of the aliens' language indicates that they are about to return, the plane crashes into Hangar 18, creating a huge explosion. The next day, a news report says that Bancroft, Forbes and their group of technicians survived the blast, shielded inside an alien spacecraft. Forbes schedules a press conference for that afternoon.

Set in an oppressive, post-apocalyptic future, resulting from a world-wide biological war, people live in small cement modules with little more than a computer which connects them to their job, food and entertainment. Some people work to control drones, which survey the outside world and capture humans. Darwin, a young boy is left in a pod by his mother, who promises to come back for him. After nine years, Darwin (portrayed by Nick Krause) is forced out into the real world when his module and alarm is left without power by a lightning strike and discovers truths about the world and his own life that he never dreamed of. He comes across a family in hiding living together in the wilderness, and becomes part of their family. He becomes friends with Dara, a young woman who teaches him how to speak. Darwin makes the difficult decision to leave in order to search for his mother. He finds his mother's pod and after a close encounter with a drone, realizes there's people watching, but nobody capturing. After kissing his mother goodbye, he returns to his life in the wilderness with Dara.

First Lieutenant Jake Tanner shares ICBM silo duty at a US Air Force missile base in the Mojave Desert in eastern California with Major Eugene "Sam" Denton. Denton notifies Tanner he's requesting that command reassign him, considering Tanner an unsuitable partner. The pair interact with Sergeant Tom Keegan while passing through base security checks. During Denton and Tanner's procedure drills, the US detects incoming nuclear missiles from the Soviet Union. Tanner and Denton launch their silo's missiles, part of a massive retaliatory strike. Despite the work of interceptor missiles, the United States suffers heavily from the Soviet attack. Two years later, the Earth has been tilted off its axis by the nuclear detonations of World War III, the planet is wracked by massive storms, and the sky is in a perpetual aurora borealis -like state. Tanner has resigned his commission and has been scouting nearby Barstow, California, while Keegan has also resigned to become an artist in one of the base's out-buildings they've been relegated to. Mutated giant scorpions menace the area, requiring Tanner and Keegan to defend the area with high-powered rifles. Airman Haskins starts a small fire by falling asleep and dropping a lit cigarette. A resulting explosion kills most of the barracks' inhabitants including the base commander, General Landers. Keegan, Tanner, Denton and Lieutenant Tom Perry survive. Denton suggests traveling to Albany, New York, to investigate a lone radio transmission that has aired weekly since the war. The survivors set out in two large 12-wheel Landmaster armored personnel carriers, in which they must cross Damnation Alley, "the path of least resistance" between intense radiation areas. Perry is killed in a storm which disables one of the Landmasters, and they encounter mutated cockroaches in the ruins of Salt Lake City that trap and eat Keegan alive. Denton and Tanner pick up two survivors: a woman in Las Vegas, Janice, and a teenage boy, Billy, discovered in an abandoned house in the High Plains. They fight gun-toting mountain men in the ruins of a gas station in the Midwest, and Denton destroys the madmen's buildings with the Landmaster's rocket launchers. The Landmaster suffers drivetrain trouble near Detroit and enters a large wrecking yard in search of replacement parts. A hemisphere-wide storm breaks, and the group shelters in the vehicle as a megatsunami washes them away, leaving them adrift in a large body of water. It appears the Earth has returned to its normal axis as the sky is suddenly clear. They drive the amphibious Landmaster onto land, and they hear a radio broadcast with music and an attempt to reach survivors. After Denton makes radio contact, Tanner and Billy set out on Tanner's dirt bike to locate the source of the broadcast. In the final scene, they reach a surprisingly intact suburb of Albany, New York, where they are greeted by its inhabitants.

Dagny Taggart pilots an airplane in pursuit of another plane. Dagny asks herself, "Who is John Galt ?" before apparently crashing into a mountainside. Nine months earlier, Dagny is trying to understand the abandoned prototype of an advanced motor she and her lover Hank Rearden have found. Scientists across the country have been disappearing under mysterious circumstances, but Dagny is able to locate Quentin Daniels, who agrees to help from an abandoned laboratory in Utah. Dagny's brother James Taggart, president of the family railroad company, meets store clerk Cherryl Brooks and brings her to see a renowned pianist, who disappears during his performance, leaving a note asking, "Who is John Galt?" Later, at James and Cherryl's wedding, Dagny's friend Francisco d'Anconia argues with other guests about whether money is evil, and secretly informs Rearden about devastating explosions at his copper mine —the next day. Rearden spends the night with Dagny. Later, he is confronted about the affair by his wife Lillian, but when he offers a divorce she declines, in order to maintain her position in society. Rearden sells his advanced Rearden Metal to Ken Danagger's coal mining company, but refuses to sell it to the federal government, in defiance of the newly enacted "Fair Share" law that forces businesses to sell to all buyers. The two are charged under the law. Dagny barges into Danagger's office, realizes that he too is about to disappear, and understands that she is close to understanding the force behind the disappearances. At trial, Rearden defends individual freedom and the pursuit of profit, and is given only a token penalty by the court, which fears turning him into a martyr. The government announces "Directive 10-289", which freezes employment and production and requires that all patents be gifted to the government. Rearden defies this decree as well, but relents when he is blackmailed with photos of himself and Dagny that would damage Dagny's reputation. When Dagny hears about Rearden's "gift" and her brother's complicity, she quits the railroad. During her absence, a Taggart Transcontinental train collides with a military train in a tunnel, due largely to political pressure by a passenger and human error by Dagny's poorly trained replacement. This impels Dagny back to her job. D'Anconia tries to dissuade her from returning, as he had earlier tried to talk Rearden into leaving his business, but she returns anyway. Dagny takes a train to Colorado to show her faith in the railway, but its engine fails. The repair technician used to work for 20th Century Motor Company, which produced the motor Dagny found. He tells Dagny how the need-based reward system in his company failed, and his coworker John Galt left the company vowing to "stop the motor of the world". Dagny calls Daniels, who tells her that he is quitting. Dagny buys a small airplane and flies to Utah to try to dissuade him, but as she is landing, she sees him get into a plane on the airstrip. After a pursuit in the air—the opening scene of the film—Dagny's plane crashes in a valley hidden by stealth technology. A wounded Dagny Taggart crawls to the edge of her crashed plane, where she is greeted by John Galt. The film ends with a quote from Ayn Rand: "Money is the barometer of a society's virtue. But when you see that in order to produce it, you need to obtain permission from those who produce nothing... You will know that your society is doomed.

Absentminded professor Philip Brainard is developing a new energy source, hoping to save Medfield College from closure. His preoccupation with his research has caused him to miss two wedding dates, much to the ire of his fiancée, college president Sara Jean Reynolds. On their third attempted wedding day, Brainard is approached by his former partner Wilson Croft of rival Rutland College, who has profited from stealing his ideas and now intends to steal Sara. While preparing for the wedding, Brainard has a breakthrough with the help of his robot assistant Weebo, who is secretly in love with him. Their experiment results in a sentient green goo with enormous elasticity and kinetic energy, which wreaks havoc on the neighborhood before the professor recaptures it. Weebo classifies the substance as "flying rubber", leading Brainard to christen it "Flubber". Working on Flubber into the following morning, Brainard realizes too late that he has again missed his own wedding. He unsuccessfully attempts to explain his absence to a heartbroken Sara, leaving Brainard determined to prove Flubber's worth and win her back. Medfield College's wealthy sponsor Chester Hoenicker, who is threatening to close the school, sends his henchmen Smith and Wesson to persuade Brainard to give Hoenicker's entitled son Bennett a better grade. Brainard, too busy experimenting with Flubber, unknowingly subdues the goons with a Flubber-coated golf ball and bowling ball. Brainard also uses Flubber to enable his vintage Ford Thunderbird to fly, and overhears Wilson make a flirtatious bet with Sara about Medfield's upcoming basketball game against Rutland. Struggling to confess her feelings for the professor, Weebo creates a holographic human version of herself and tries to kiss a sleeping Brainard, but he awakens with another idea for Flubber. Sneaking into the vacant basketball arena, he tests the effects of Flubber on a basketball and his shoes, allowing him to bounce incredibly far. At the game, he secretly applies Flubber to the abysmally unskilled Medfield team, enabling them to beat Rutland, but his attempt to win back Sara fails. Meanwhile, a mischievous Weebo releases Flubber to dance around the house. Returning home, Brainard talks to Weebo, declaring that his absentmindedness is due to his love for Sara. Weebo, putting the professor's happiness before her own, shows Sara footage of Brainard's declaration, and the couple reconciles. Brainard demonstrates Flubber's abilities to Sara, but Hoenicker has discovered Flubber's profitable potential, offering to buy it and forgive the college's debt. Brainard and Sara refuse, making a deal with the Ford Motor Company instead and saving the college. Hoenicker sends Smith and Wesson to raid Brainard's house, where Weebo attempts to fend them off but is destroyed as they steal Flubber. Mourning the loss of his beloved robot, Brainard discovers a farewell video from Weebo along with a backup of herself, her "daughter" Weebette. Brainard and Sara confront Hoenicker under the guise of selling him additional Flubber, and discover he is in league with Wilson. Unleashing Flubber, Brainard and Sara defeat Wilson, the Hoenickers, and their henchmen. Sometime later, Brainard saves Medfield from closing with Flubber and the happy couple finally have a successful wedding and embark on their honeymoon to Hawaii in the flying Ford Thunderbird with Weebette and Flubber.

The film begins with the alien abduction on Scalleum, a remote island off the coast of Wales, of Cat Williams and her boyfriend. Cat's boyfriend is gorily killed through brutal anal probing, and Cat is (also gorily) implanted with an alien fetus. Cat's story attracts the attention of Michelle "Foxy" Fox, the bosomy host of the cable TV show Weird Worlde, who brings a film crew to the island — her cameraman boyfriend Ricky; Jack the sound man; nerdy UFO expert Gavin Gorman; and actors Bruce Barton and Candy Vixen (the latter, Foxy's producer assures her, "because she's good, not because she's my girlfriend"). The island is accessible via a narrow causeway only at low tide. The Weird Worlde crew sets out in their van, but it is dark by the time they reach the Williams family's creepy farmhouse, where they meet Cat and her three hulking and sadistic brothers (who speak only Welsh with English subtitles). The crew (with the exception of Gavin Gorman) initially assume that Cat's story is a hoax, and even go so far as to make a crop circle in a nearby field so they can film it for the show, to Gorman's great disgust. However, it soon turns out that the aliens are all too real and rather malevolent. The film crew teams up with the Welsh Williams brothers to fight off the aliens, with a great deal of blood and gore. One highlight features Ricky running down some aliens in a combine harvester, to the tune of " Combine Harvester (Brand New Key) " by The Wurzels. Eventually, the alien child inside Cat claws its way out; on board the alien ship, Foxy is impregnated with another alien fetus while Gavin loses his virginity to a shapely female alien; Bruce, Candy, and the Welsh brothers meet various horrible demises; Ricky blows up himself and four alien pursuers in a tank of liquid manure; back at the house, the female alien rips Foxy in half; and finally Gavin manages to use his laptop (in a sequence reminiscent of Independence Day) to overload the ley lines of the nearby stone circle. As Cat's alien child rips his arms off, Gavin manages to press the space bar with his nose, sending the stones shooting into the underside of the alien craft, which crashes into a convenient mountain. Jack the sound man, meanwhile, having been blinded by alien ichor early in the film, swims across the channel to the mainland, only to discover that he's lost the videotape that was the only proof of their extraterrestrial encounter. The film ends with a clip from an alien talk show reminiscent of Jerry Springer (and subtitled in English), on which Gavin's female alien is trying to explain how her entire crew was killed by humans and she herself carries the love child of one of those humans. The audience roars with laughter, and the host cuts her mike.

Fox and X are Tokyo-based freelance industrial spies who specialize in helping R&D scientists defect from corporations who would rather see them dead than working for competitors. Fox is obsessed with Dr. Hiroshi, a paradigm-shattering super-genius who works for Maas, the German corporation that crippled Fox. Japanese firm Hosaka hires Fox and X to help Hiroshi defect, offering a fee of $50 million. Fox and X hire Sandii, a nightclub singer and call girl in Shinjuku, to help persuade Hiroshi to defect to a newly outfitted Hosaka lab in Marrakesh. While training her for the extraction, X falls in love with Sandii, who offers conflicting accounts of her past. Fox and X meet Hosaka representatives and negotiate their fee up to $100 million. Sandii meets Hiroshi in Vienna and persuades him to leave his wife and defect to Hosaka. Fox travels to Marrakesh to await Hiroshi, and X arranges to spend a night with Sandii in Berlin before her rendezvous in Marrakesh. Sandii proposes that she and X leave Fox and marry. X offers to discuss it after Sandii visits Marrakesh. That night, while Sandii sleeps, X rummages through her personal effects, finding cash, information about her aliases, and an unmarked computer chip. Hosaka transfers the agreed-upon $100 million fee. Fox returns from Marrakesh, and X informs him that he will be meeting Sandii in Shinjuku to start a new life with her, a plan that Fox begrudgingly accepts. Later, Fox and X celebrate their success and newfound wealth with prostitutes. The next day, X's contact in Marrakesh informs him that Hosaka has relocated many top scientists to the new lab in Marrakesh, a move that Fox deems unsafe but potentially lucrative for him and X, despite X's insistence that he is finished with the case. During the night, X's Marrakesh contact informs him that somebody secretly reprogrammed the lab's DNA synthesizer to spread a virus that killed everyone in the facility, including Hiroshi, and that Sandii has vanished. X discovers that the bank account holding the $100 million has been terminated. Fox deduces that Maas recruited Sandii in Vienna and ordered her to kill Hosaka's scientists in Marrakesh, and that Hosaka, presuming that Fox and X were complicit, has wiped their account and will send agents to kill them. After being surrounded by Hosaka agents in a department store, Fox leaps to his death. X flees to a shabby capsule hotel called the New Rose Hotel, where he reflects on his time with Fox and Sandii and views footage of a man removing the unmarked computer chip from the DNA synthesizer in Marrakesh. Knowing that Hosaka will hunt him wherever he goes, X contemplates suicide and masturbates to the memory of his last night with Sandii.

Two years after the Apollo 17 mission, the crew of the cancelled Apollo 18 mission consisting of Commander Nathan Walker, Lieutenant Colonel John Grey, and Captain Ben Anderson are informed that it will proceed as a top-secret Department of Defense (DoD) mission to place an early warning detector on the Moon for ICBM attacks from the USSR. Grey remains aboard Apollo command module Freedom while Walker and Anderson land in Apollo Lunar Module Liberty to plant the detector. Anderson takes back rock samples and the two return to Liberty. The samples cause small disturbances, which Houston attributes to interference from the detector. The next day, Anderson discovers footprints that lead them to an abandoned but functioning Soviet LK lander. They discover a crater with a dead cosmonaut, to which Houston dismisses Walker's queries. While sleeping, Walker is awakened by strange noises and an object bumping into the lander. Walker and Anderson complete the mission and prepare to leave, but the launch is aborted when Liberty suffers violent shaking, which they discover is a result of damaged foil. Nearby, they find non-human tracks outside the Liberty alongside damaged equipment. Walker is horrified at a spider-like creature that has entered his spacesuit and disappears before Anderson finds him unconscious near Liberty, which Walker later denies happening. Later, Anderson removes a Moon rock embedded in Walker. Walker smashes the rock, contaminating the ship. Due to interference from an unknown source, the two are unable to contact Houston or Grey. Anderson speculates that the device is meant to monitor the aliens and that it is the source of the interference. They attempt to deactivate the device but find it destroyed. Walker begins to become contentious and paranoid, and they discover that the aliens are camouflaged as Moon rocks. In an attempt to destroy the cameras inside Liberty, Walker destroys other controls, causing the ship to depressurize. While traveling to the Soviet LK lander to get oxygen, Walker intentionally crashes the rover, believing that he will spread the infection on Earth if he were to return. Anderson awakens and finds Walker getting pulled into a crater by the aliens. Anderson fails to rescue him and flees to the Soviet LK. He uses the radio to contact the USSR Mission Control, who connect him to the DoD. The Deputy Secretary informs Anderson that they cannot allow him to return to Earth, admitting that they are aware of the situation and incorrectly believe that he is also infected. Grey contacts Anderson, and they plan to return him to Freedom. As Anderson prepares to launch, Walker suddenly appears and demands to be let in before being suddenly swarmed by the aliens, who kill him. Anderson launches, but the DoD informs Grey that he is to abort the rescue, or they will not allow him to return either. The LK enters orbit and, while in free fall, the aliens attack and infect Anderson. Anderson is unable to control the ship, and he collides with Freedom. The U.S. government states that the astronauts were killed in various jet accidents that left their bodies unrecoverable. They note that many of the rock samples returned from previous Apollo missions given to dignitaries are now missing.

In 2011, astronauts Brian Harper, Jocinda "Jo" Fowler, and Alan Marcus are on a Space Shuttle mission to repair a satellite. A mysterious swarm of alien technology attacks the orbiter, killing Alan and knocking Jo unconscious before tunneling into the surface of the Moon. Brian, the only witness to the swarm, returns the crippled shuttle to Earth, but his story is dismissed, and he is fired from NASA. Ten years later, conspiracy theorist K.C. Houseman, who believes that the Moon is an artificial megastructure, surreptitiously gains access to a research telescope. He discovers that the Moon's orbit is veering closer to Earth. He tries to share his findings with Brian. NASA also discovers the anomaly. K.C. anonymously announces his observation on social media, which leads to a global panic. Jo, now NASA's deputy director, launches a spacecraft on an SLS Block 1B+ rocket to investigate the abnormality. After the astronauts drop a probe into a miles-deep artificial shaft that has opened up on the Moon's surface, the alien swarm attacks, killing all three lunar astronauts. The lunar orbit continues to decay, and as the Moon falls closer and closer to the Earth, seismic and gravitational disturbances occur. Jo meets former NASA official Holdenfield, who reveals that Brian was discredited because of a NASA coverup dating back to Apollo 11. During the first Moon landing, a two-minute radio blackout was meant to conceal evidence of pulsating lights on the Moon's surface. Apollo 12 revealed that the Moon is hollow. A military electromagnetic pulse (EMP) device was created to eliminate the swarm, but the project was abandoned for budgetary reasons. With help from her ex-husband General Doug Davidson, Air Force Chief of Staff, Jo requisitions the EMP and commandeers retired Space Shuttle Endeavour from a museum to serve the new mission: to correct the Moon's orbit and destroy the swarm. Brian, K.C., and Jo launch with the EMP, using the Moon's gravity, narrowly escaping to orbit as a tsunami destroys Vandenberg Air Force Base. They reach the interior of the Moon, revealed to be a Dyson sphere powered by a white dwarf at its center. The Dyson sphere's AI operating system explains to Brian that billions of years ago, the technologically advanced ancestors of modern humans created the AI swarm to serve them, but upon becoming self aware, it went rogue and they were eradicated by it. They built the Moon as an interstellar ark to create the Earth and then seed life on it, but the AI swarm discovered it and began siphoning energy from its power source, destabilizing its orbit. Meanwhile, Brian's son Sonny, Jo's son Jimmy, and Jimmy's caretaker Michelle try to reach Doug's military bunker in the Colorado mountains. They find Brian's ex-wife and Sonny's mother Brenda, her husband Tom, and their family. They avoid disasters caused by the Moon's proximity and fight other hostile survivors, then reach safety in a mountain tunnel. As the Moon strips away the local atmosphere, Tom's youngest daughter runs out of oxygen. The injured Tom gives her his own supply; he suffocates to death. The President of the United States orders a nuclear strike on the approaching Moon, but Doug refuses to comply, with debris collapsing the bunker shortly thereafter, apparently killing everyone inside. As the swarm attacks all electronic objects containing organic life inside, K.C. lures the swarm away from their spacecraft with their lunar module, sacrificing himself to detonate the EMP. Jo and Brian return to Earth, reuniting with their families, and the Moon's power is restored, returning to its regular orbit, but now shed of its rocky exterior. Reconstructing K.C.'s consciousness, the Moon's operating system appears to K.C. as his cat Fuzz Aldrin and his mother, who remarks that they must now "get started".

John, now going by the surname Young, teaches comparative religion at a community college in Chico, California. He is well-liked by students and married to fellow faculty member Carolyn Kittriss. For the first time in his life, John shows signs of ageing and a cut during a hunting trip indicates that his regenerative abilities are diminishing. When Isabel, an enthusiastic student, is allowed to borrow books from John's collection, she discovers one authored by Dr. Jenkins and signed for John Oldman. Curious, Isabel learns about another, controversial book he authored, an account of the 14,000-year-old John Oldman. Drawing parallels between Oldman and their teacher, she shares the discovery with her classmates Tara, Liko and Philip. They are open to the possibility that they are the same person, although Philip's faith is challenged with the book's claim that John was Jesus Christ (another possibility is that he may have been the Teacher of Righteousness). Their suspicions are confirmed when they obtain the book and see the only photo of Oldman, who is described as averse to being photographed to facilitate forging new identities. Isabel attempts to contact Dr. Jenkins by email, but he rudely rejects her, assuming she is yet another person seeking to ridicule him. Undeterred, Isabel, Tara and Liko trespass into the Young household, discovering several books authored by John under various surnames. They also find a painting believed to be by Vincent van Gogh, which Isabel's cousin, an art major, considers possibly authentic supporting the book's claim that John had known van Gogh personally. The group later contacts a retired university professor who recalls meeting John during the 1950s. Isabel leaves a voice message for Jenkins, but this time he is interested when she mentions John Young and agrees to meet them on the condition that they first provide a clear photo of John's face. After unsuccessful attempts to take a picture in class, they go into his house at night and photograph him while he is asleep. Jenkins, although somewhat hesitant as the purported John appears aged, agrees. Shortly afterward, Tara visits John in his office. He becomes concerned when she cryptically claims to know his true identity. In tears, Tara explains that she has always felt lonely as well. When John attempts to comfort her, she makes a sexual advance, which he rejects, asking her to leave. Isabel scolds Tara when she confesses the incident, fearing that John may leave before Jenkins arrives. John is indeed preparing for departure, and his refusal to offer an explanation leads to an argument with his wife. That evening, the four confront John about the book's veracity. He admits to being Oldman but insists that the story was a fabrication and expresses regret that Jenkins damaged his own reputation by publishing it. To stop him, John is tased and restrained in his basement, assigning Philip to watch him while the others attempt to retrieve Jenkins, whose car has broken down nearby. Upon regaining consciousness, John warns Philip that their actions are criminal but offers not to report them if he is released. Philip, however, persists in questioning John about Jesus. After a few evasions, John finally admits to having been Jesus, explaining that he has avoided garnering attention since witnessing the distortion of his moral teachings. Although Philip initially welcomes the idea that John is divine despite telling the truth, the situation becomes tense when John expresses that all religious paths lead to salvation. Recounting the Book of Revelation, Philip renounces John as the seven-headed beast and stabs him. When Jenkins, Isabel, Liko and Tara arrive, they are shocked to find blood stains throughout the house, with both John and Philip missing. Weeks later, John has been hiding in the wilderness, and he arranges to meet with Harry. They speculate that his aging might result from the Holocene itself ending to herald the Anthropocene. John accepts Harry's invitation to live with his family. Back in his home, Jenkins is visited by an FBI agent who knows about John's many identities and extraordinary age, adding that he is a suspect in many violent crimes, including Philip's disappearance. When he asks Jenkins whether he believes an immortal serial killer is possible, Jenkins replies that anything is.

In 1947 New Mexico, a radio operator receives a bizarre signal coming from Roswell, New Mexico. He decides to investigate its origin and disappears tracking it. In the present day, the same signal is received from the South Pole and then retransmitted from the Falkland Islands to the United States. A satellite image captures an unknown object sitting on the Antarctic snow. Cryptologist Julian Rome, a teacher at the University of California, Berkeley, is invited to investigate the mystery. He is sent to an Antarctic research base, which includes a large greenhouse of genetically modified plants being studied by scientists. They discover what appears to be an alien vehicle frozen in a large block of ice. The object is shaped like a shell or pod and is emitting the mysterious encrypted signal. Once it is released from the ice, Julian discovers that it has a powerful static electric charge on its surface and painfully shocks anyone who touches it. Julian tries to decrypt the signal (which soon proves to be: "Do not open!"), while another team works to open the alien shell. They succeed in cutting off the lid, which allows a viscous liquid to pour out. An alien also escapes, while at the same time an airborne virus sealed in the shell kills four scientists by melting them from within. The virus also kills all the plants, making them wilt and turn brown. The virus has an unusually high speed of transmission and extreme virulence. It kills anyone within a few minutes of exposure. The government is aware of the alien virus and the global risk that it poses. They ask a Russian nuclear submarine to fire a nuclear missile at the base before the threat can spread. As the submarine nears its firing position, Julian manages to communicate with the alien, before it is killed by one of the survivors. Julian realizes that if any of the survivors leave the base alive, the lethal alien virus will cause a pandemic destroying all life on Earth. Just a few seconds before the missile hits, he and three others, Shelly, Kate, and Dr. Gierach, are rescued from the base by an alien spacecraft (which had homed in on the same signal Julian was studying). In the aftermath, the government mounts a cover-up campaign by claiming that an experimental nuclear reactor at the base went into meltdown, destroying all of the facilities and killing everyone. The film ends with the alien spacecraft, still carrying the human survivors, leaving the Solar System.
