In the distant future, an overcrowded and troubled Earth relies on research conducted by scientists in remote stations across the Solar System. Contact is maintained by spaceships shuttling between the stations and large orbiting space stations. Captain James is preparing to depart from one of these stations around Saturn when he is murdered by Captain Benson. Benson, who was rated "potentially unstable" on a mental exam, then departs from the station using his cargo ship for a small, remote experimental hydroponics research station called Saturn 3. Arriving there, he finds the station run solely by Adam and his younger colleague and lover, Alex. Adam, Alex, and their dog, Sally, enjoy their isolation away from Earth. Alex has spent her entire life in space and knows Earth only from what Adam has told her. It falls to Benson to more fully educate Alex as to the habits and mores of humans who live on Earth, which include drug use. Alex and Adam's idyll is broken when Benson reveals his mission is to replace at least one of the moon's scientists with a robot. The robot—named Hector—is among the first of its kind, a "Demigod Series" model that relies on "pure brain tissue" extracted from human fetuses and is programmed via a direct link to Benson's brain. Adam tells Alex that he is the likely candidate for removal, being that he is close to "abort time" and will have to leave anyway. With Hector assembled, Benson begins preparing the robot, using the neural link implanted in his spine. Thus connected to Benson, Hector quickly learns of Benson's failure of the psychological stability test, and also of his murder of James. With little barrier between the robot's brain and Benson's, Hector is soon imbued with Benson's homicidal nature and his lust for Alex. The robot rebels. Adam and Benson disable the robot while it is recharging and remove its brain. Believing the danger is over, Adam accuses Benson of gross incompetence and orders him to dismantle the robot and return to Earth when the eclipse ends (the eclipse also prevents communication with other stations). Unknown to Benson, Adam, and Alex, Hector remains functional enough to take control of the base's older robots and use them to reassemble his body and reconnect his brain. Unaware of Hector's resurgence, Benson attempts to leave the station while dragging Alex with him. Resuscitated, Hector murders Benson before he can leave with Alex. Hector destroys Benson's spacecraft before the scientists can escape in it, trapping them all on Saturn 3, and assumes control of the station's computer. Trapped in the control room, both Alex and Adam are surprised to see Benson's face on their monitor. The two are directed by a voice they recognise as Benson's to leave the control room, both surprised that Benson is even alive. To their shock, the two are confronted by Hector, now wearing Benson's severed head. A short time later, Alex and Adam wake in their own rooms. To her horror, Alex finds that Hector has installed a brain link at the top of Adam's spine, much like the one that Benson had, and one which will give Hector direct access to Adam's brain. Hector explains that he can 'read' but taking control of Adam 'comes later'. This causes Adam to rebel, and he destroys Hector by tackling him into a waste pit and sacrificing himself with a grenade. In the final scene, Alex is shown aboard a passenger ship returning to Earth. She declines an offer of narcotics from a stewardess and instead looks out of a window for her first glimpse of Earth.

In the near future, the U.S. Navy develops the F/A-37 Talon, a single-seat strike fighter with advanced payload, range, speed, and stealth capabilities. The program recruits three pilots out of 400 applicants; Lieutenants Ben Gannon, Kara Wade, and Henry Purcell. Captain George Cummings is the overall head. To further advance the program, Cummings has an artificial intelligence, the " Extreme Deep Invader " (EDI), installed on an autonomous aircraft. EDI joins the others on the USS Abraham Lincoln in the Philippine Sea to learn combat maneuvers from the pilots. This sparks controversy over a machine's inability to make moral decisions versus the human struggle to overcome ego. While training EDI in air combat maneuvers, the team is unexpectedly reassigned to kill the commanders of three terrorist cells at a conference in downtown Rangoon. According to EDI's calculation, minimum collateral damage can only be achieved by a vertical missile strike augmented by the bomber diving at a speed sufficient to cause a human pilot to black out. Command authorizes EDI to attack, but Gannon defies orders and carries out the attack himself, blacking out and regaining consciousness just in time to avoid crashing. As the team returns to the Lincoln, EDI is hit by lightning. Subsequent inspection of EDI reveals an accelerated learning pace and development of a rudimentary ethical code and an ego, which might lead to unpredictable behaviors, but Cummings refuses to take EDI offline. During a mission to destroy stolen nuclear warheads in Tajikistan, Wade realizes that the fallout will cause significant civilian casualties. The human pilots abort, but EDI defies orders and destroys the warheads, causing extensive radioactive fallout and the anticipated casualties. After EDI refuses to return to base, an agitated Gannon decides to shoot it down. In the ensuing dogfight, a missile Purcell fires at EDI explodes on a mountain, blinding him and causing a fatal crash. Wade's plane is damaged by the same explosion, which triggers her plane's self-destruct, and in turn forces her to eject over North Korea. Command realizes EDI is executing a 20-year-old war scenario called 'Caviar Sweep' that involves attacking Russia. Gannon chases EDI into Russian territory where they destroy several Russian Su-37s. After both planes are damaged, Gannon calls a truce with EDI to avoid falling into enemy hands and rescue Wade. Cummings instructs the two to land in Alaska. At risk of facing court-martial for ignoring EDI's behavior, Cummings seeks to eliminate witnesses. He ignores Wade, who heads to the Korean Demilitarized Zone – while evading the army. Cummings orders Gannon eliminated, and orders Dr. Keith Orbit, EDI's creator, to Alaska to wipe EDI's memory. At the Alaskan base, suspecting Cummings' treachery, Gannon narrowly escapes an assassination attempt by the base's doctor and kills him in self defense. Meanwhile, while Orbit inspects EDI, the AI expresses regret for its transgressions. Realizing EDI has developed sentience, Orbit disregards Cumming's order to erase its memory. Orbit reinstalls EDI and Gannon climbs in the same plane as his was damaged during landing. Gannon uses EDI's weapons systems to clear a path for Orbit to flee, then flies to North Korea. Gannon contacts the Lincoln ' s skipper, Captain Dick Marshfield, to inform him about Cummings' deceit. Before Marshfield can order him arrested and court-martialed, Cummings commits suicide. Gannon finds the injured and embattled Wade nearing the border. He lands and runs to her aid. Out of ammunition and taking damage from an Mi-8 helicopter, EDI sacrifices itself by ramming the helicopter, destroying both. Gannon and Wade cross on foot into South Korea, where they are rescued. After attending Purcell's funeral, Gannon awkwardly expresses his feelings of love to Wade. In a post-credits scene, in the debris-strewn border between North and South Korea, EDI's "brain" is seen turning back on.

Patrick, Tim, and Georgie are firefighters who live and work together. After saving two children from a fire, they are hailed as heroes of New Orleans. While on a fishing trip with his girlfriend Sophia, Patrick claims to witness a 35-foot long shark. Although he repeatedly tries to warn his friends, they do not believe him and insist there are no sharks in the Mississippi River. Eventually, Patrick is vindicated when shark attacks are reported on the local news. The shark is carried abreast of flood water through the streets of the city, eating people. Patrick and Tim set out across New Orleans to save the city from the shark, and scenes in which they search for or flee from it are interspersed with scenes of interactions with their girlfriends and socializing at a bar. Meanwhile, their boss, Captain Joe, procures scuba gear for them and implores them to help save the city. Tim receives a treasure map from an old man in the bar, marking where the shark sleeps, though Patrick expresses some confusion over whether or not sharks sleep. While playing pool, Patrick and Tim conceive a plan to place a tracking device on the shark, follow it in their scuba gear, and feed it dynamite hidden inside a pig carcass. After obtaining the bait, they spear the shark with the tracking device, but the animal retaliates and eats Georgie. Tim and Patrick visit a shrine erected in Georgie's honor on the beach, and together mourn their friend's death by composing a song. With the tracking device in place, Tim and Patrick pursue the shark into the bayou and kill it by tricking it into eating the bomb. Initially, Tim seems to die in the explosion, but it is revealed that he was only flung high in the air and survives. The heroes celebrate by dancing in the streets of New Orleans with a marching band.

In New York City 's Central Park, people begin committing mass suicide. The event is believed to be caused by a bio-terrorist attack using an airborne neurotoxin. The behavior quickly spreads across the Northeastern United States. High school science teacher Elliot Moore and his wife Alma are persuaded by Elliot's mathematician colleague Julian to accompany him and his daughter Jess on a train out of Philadelphia. During the trip, the group learns Boston and Philadelphia have been affected. The train loses all radio contact and stops at a small town. When Julian learns his wife has left Boston for Princeton, he decides to look for her and entrusts Jess to the Moores. However, Julian arrives to find Princeton has been affected, causing the driver of the car in which he is riding to ram into a tree. Julian survives but commits suicide by slitting his wrist with a glass shard. Elliot, Alma, and Jess hitch a ride with a nurseryman and his wife. The nurseryman hypothesizes that plant life has developed a defense mechanism against humans consisting of an airborne toxin that stimulates neurotransmitters and causes humans to kill themselves. The group is later joined by other survivors coming from various directions, and the small crowd chooses to avoid roads and populated areas. When the larger part of the group is affected by the toxin, Elliot suggests the nurseryman was right and the plants are targeting only large groups of people. He splits their group into smaller pockets and they walk along. The trio ends up with a pair of teenage boys, Josh and Jared, who are later shot and killed by the armed residents of a barricaded house. Elliot, Alma, and Jess wander the countryside and come upon the home of Mrs. Jones, an eccentric and paranoid elderly woman. Jones initially agrees to house the group for the night but is suspicious of them having bad intentions; the next morning, she decides to expel them. In a fury, she leaves the house alone and is affected by the toxin. The shaken Elliot realizes the plants are now targeting individuals. Left with no option when Mrs. Jones strikes her head into several windows, the trio chooses to die and embraces in the yard only to find themselves unaffected by the toxin. The outbreak has abated as quickly as it began. Three months later, Elliot and Alma have adjusted to their new life with Jess as their adopted daughter. Alma learns she is pregnant and surprises Elliot with the news. On television, an expert compares the natural event to a red tide and warns the epidemic may have only been a harbinger of an impending global disaster. In Paris 's Tuileries Gardens, people begin committing mass suicide.

The conglomerate Webscoe Industries hires computer programmer Gus Gorman, who secretly embezzles $85,000 from the company payroll. Gus comes to the attention of Webscoe's CEO, Ross Webster. A cunning billionaire fixated on using technology for financial domination, Webster sees Gus's skills as a valuable asset. With the help of his stern sister, Vera, and his mistress Lorelei Ambrosia, he blackmails Gus into aiding his schemes. Superman extinguishes a fire in a chemical plant, and, as Clark Kent, he returns to Smallville for his high school reunion. Clark reconnects with childhood friend Lana Lang, who has a young son named Ricky. Superman later saves Ricky from a combine harvester accident during a picnic with Lana. Webster orders Gus to use the weather satellite 'Vulcan' to create a storm that destroys coffee crops in Colombia, aiming to corner the market. Gus complies, but Superman neutralizes the storm. Recognizing Superman as a threat, Webster orders Gus to synthesize Kryptonite. When the computer fails to recognize the total chemical composition, Gus substitutes tar for the unknown elements. Lana invites Superman to Ricky's birthday party. Gus and Vera infiltrate the party and give Superman the synthetic Kryptonite, which leaves him unharmed, to their confusion. Instead, he gradually becomes corrupted after exposure to it, committing sophomoric acts such as straightening the Leaning Tower of Pisa and blowing out the Olympic Flame. Gus proposes building a supercomputer for Webster in exchange for creating an energy crisis by redirecting oil tankers. Lorelei seduces Superman and manipulates him into causing an oil spill. Superman suffers a nervous breakdown and splits into two beings: the corrupted Superman and Clark Kent. The two fight, and Clark defeats his corrupted counterpart by strangling him to death. Superman then repairs the damage of the oil spill. After surviving exploding rockets and a missile, he confronts Webster, Vera, and Lorelei in the supercomputer. The computer becomes self-aware and defends itself against attempts to disable it as it transforms Vera into a cyborg. Vera attacks Webster and Lorelei with energy beams that immobilize them. Superman retrieves a can of acid from the chemical plant and uses it to destroy the computer. Superman hands Webster and cronies to the authorities. Gus starts anew in West Virginia. Meanwhile, Clark visits Lana in Metropolis, where she begins working as a secretary for Perry White. Lois Lane returns from Bermuda with an exposé on corruption, and Superman restores the Leaning Tower of Pisa before flying into space.

The year is 2047, 29 years after the nuclear war immediately following the battle between the Earth and Moon Nazis rendered the planet inhospitable. The last survivors have rallied together on "Neomenia", the former Moon Nazi base on the far side of the Moon, struggling to coexist with the former Moon Nazis who also live in the base. Over the years, the base has started to deteriorate, due to overpopulation and the damage on the Moon caused by the battle. Meanwhile, Jobsism, a cult formed around the teachings of Steve Jobs and their leader, Donald, has become the Moon base's official religion. Obi Washington, daughter of James Washington (who has since passed away) and Renate Richter, has spent her life keeping Neomenia's life support systems functional. While examining a Russian refugee ship, she encounters Wolfgang Kortzfleisch, the long-presumed-dead former Moonführer, who gives her Vrilia, the cure to Renate's terminal illness. When Renate's health is restored, Kortzfleisch reveals to Obi that he is a Vril, a race of Reptilians that arrived on Earth during the age of the dinosaurs. While studying the primates that emerged during prehistory, Kortzfleisch created humankind by injecting Vrilia into an apple and feeding it to his monkeys, Adam and Eve. The Vril have since gone underground to the center of the Earth once mankind had evolved. Kortzfleisch offers Obi a mission to travel to the subterranean city of Agartha and take the city's Vrilia to ensure the survival of her colony. Obi, along with the refugee ship's pilot, Sasha, security officer Malcolm, and the Jobsists, fly to Antarctica and crash in the Hollow Earth. In Agartha, the Vril, who have been masquerading as world leaders throughout history, kill the President of the United States for making the surface world uninhabitable. The Jobsists and Malcolm are captured by Steve Jobs and brought to Adolf Hitler, and Donald offers Hitler the whereabouts of Kortzfleisch in exchange for the Jobsists to live in Agartha, only for Hitler to betray them and have Jobs eat the Jobsists. Meanwhile, Obi and Sasha take the Holy Grail, the source of the Vrilia, but cause Agartha's sun to collapse and destroy the city. Malcolm escapes from captivity and rejoins Obi and Sasha before they fly back to Neomenia. Hitler launches the Vril spaceship out of Antarctica to follow them. Upon the trio's arrival, Kortzfleisch holds Renate hostage for Obi to surrender the Holy Grail, but Hitler and his pet Tyrannosaurus, Blondi, invade the Moon base. After drinking from the Holy Grail, a rejuvenated Renate confronts and kills Hitler, but is mortally wounded by Kortzfleisch. Obi, Sasha, Malcolm, and the surviving inhabitants escape in an old ship, but Kortzfleisch chases after them. Using Sasha's old Nokia 3310, Obi hacks into Donald's iPhone, triggering the self-destruct mechanism and destroying the Vril spaceship. During dinner, Malcolm comes out as gay, but collapses and seemingly dies from allergens in the food. Both he and Renate are given a space funeral, but Malcolm suddenly gets out of his coffin, revealing that he only went into a short coma, a condition he has had since childhood. As the ship makes its long travel to Mars, Obi and Sasha express their love for each other. In a mid-credit sequence, it is revealed that Mars has been colonized by the Soviet Union.

Late at night, an elderly toy-maker reads a book to his granddaughter. In the story the Land of Oz is ruled by Prime Minister Kruel, aided by Ambassador Wikked, Lady Vishuss, and the Wizard who is a "medicine-show hokum hustler". When the discontented citiens of Oz, led by Prince Kynd, demand the return of the princess, who disappeared as a baby many years before, so she can be crowned their rightful ruler, Kruel has the Wizard distract them with a parlor trick and sends Wikked on a mission. Meanwhile, in Kansas, Dorothy lives on a farm with her relatives. Aunt Em is a kind and caring woman but Uncle Henry is a large man with a short temper who shows little affection for his niece. He acts abusive to his three farmhands, in which two of them are in love with Dorothy. Aunt Em reveals to Dorothy that she was put on their doorstep as a baby, along with an envelope and instructions that it be opened only when she turns 18. On her 18th birthday, however, Ambassador Wikked and his henchmen arrive at the farm in an airplane and demand the envelope. When Uncle Henry refuses to hand it over, Wikked persuades one of the farmhands by promising him wealth and Dorothy. Wikked has Dorothy tied to a rope and raised high up on a tower; his men start a fire underneath the rope. The farmhand finds the note, but the other takes it and saves Dorothy, only to have Wikked and his men capture them all at gunpoint. Then, a tornado suddenly strikes. Dorothy, the three farmhands, and Uncle Henry take shelter inside a small wooden shed, which is carried aloft by the violent wind and deposited in the Land of Oz. Dorothy finally reads the contents of the envelope; it declares that she is Princess Dorothea, the rightful ruler of Oz. Thwarted by her discovering this truth, Prime Minister Kruel blames the farmhands for kidnapping her and demands that the Wizard transform them into wild creatures such as a monkey, which he is unable to do. Being chased by Kruel's soldiers, one of the farmhands disguises himself as a scarecrow, while the other creates a costume from the pile of tin in which he is hiding under. However, they are still eventually captured by the soldiers. During their trial, the Tin Man accuses his fellow farmhands of kidnapping Dorothy. As judgement, Prince Kynd has the Scarecrow put in the dungeon. Kruel makes the Tin Man "Knight of the Garter" and Wikked suggests he retain his power by marrying Dorothy. The Wizard then helps the two prisoners escape by giving the third farmhand, Snowball a lion costume, which he uses to scare away the guards. Though the Scarecrow manages to reach Dorothy to warn her against Kruel, he is chased back down into the dungeon by the Tin Man, and ends up getting trapped inside a lion cage (with real lions) for a while. He and Snowball finally escape. When Prince Kynd finds Kruel trying to force Dorothy to marry him, they engage in a sword fight. When Kruel's henchmen intervene and help disarm Kynd, the Scarecrow saves Dorothy and Kynd. Defeated, Kruel claims that he took Dorothy to Kansas in order to protect her from court factions out to harm her, but she orders that he be taken away. The Scarecrow is heartbroken to discover that Dorothy has fallen for Prince Kynd. He then flees up a tower from the Tin Man, who tries to blast him with a cannon. Snowball flies a biplane overhead, and the Scarecrow manages to grab a rope ladder dangling underneath it. However, the ladder breaks and he falls. The scene shifts abruptly back to the little girl, who had fallen asleep. She wakes up and leaves. The grandfather reads from the book that Dorothy marries Prince Kynd and they live happily ever after.

A joint U.S.–South American task force is formed to counter a powerful drug cartel smuggling narcotics to the United States. However, a U.S. Army air assault on the cartel's fortified mountain compound is repelled by Eric Stoller (Bert Rhine), a skilled mercenary pilot flying a modified MD 500 Defender called the "Scorpion", who shoots down the assault force's UH-60 Black Hawks and attacks their AH-1 Cobra escorts; Jake Preston (Nicolas Cage), the sole surviving Cobra pilot, is forced to retreat. The U.S. Army plans to deploy a team of four AH-64 Apaches, which can match the Scorpion's maneuverability and firepower, to stand a better chance against the cartel and Stoller. Preston is enlisted in the Apache air-to-air combat training program led by flight instructor Brad Little (Tommy Lee Jones) and encounters Billie Lee Guthrie (Sean Young), his ex-girlfriend who broke off their relationship to pursue a separate career flying the OH-58 Kiowa scout helicopter, and has been assigned to assist the Apaches as their target designator and spotter. Preston's arrogance and loose improvised style earns him the respect and chagrin of Little, who helps him overcome an ocular dominance disability that interferes with the Apache's visual input. The Drug Enforcement Administration leads a mission to apprehend the cartel's leaders, and the Apache team deploys to South America to assist them. However, their base is attacked and an Apache is destroyed, while another Apache stays behind to cover the DEA team, leaving only Preston, Little, and Guthrie to search for Stoller. Little and Guthrie locate and engage Stoller, who is supported by a pair of Saab 35 Draken fighter jets, but Little is shot down and survives, while Guthrie is targeted by Stoller. However, Preston reaches them in time and engages Stoller, who he tricks using a mountain into exposing himself to be shot down and killed, while Guthrie uses missiles from Little's downed Apache to shoot down the remaining enemy aircraft. With the cartel's air supremacy lost, they are left vulnerable for the task force to arrest their leaders and defeat the cartel. As Little is medically evacuated, he expresses pride in both Preston and Guthrie.

In the future on a human-populated space colony, Nova Prime, the S'krell extraterrestrial race attempts to take it over with creatures called Ursas, which hunt by "sensing" fear despite being technically blind. Humanity created a peacekeeping military organization, The Ranger Corps, to fight the threat. Their leader, General Cypher Raige, defeats the Ursas with a fear-suppressing technique he called "ghosting". Cypher's daughter, Senshi, was killed during an Ursa assault. Blaming himself for his sister's death, Senshi's 14-year-old brother Kitai trains to become a Ranger like Cypher but is rejected. Kitai's mother Faia convinces Cypher to take their son on his last mission before he retires. He takes The Ranger Corps off planet to train with a live Ursa, which is tied and immobilized in their spaceship. During flight, the ship is caught in an asteroid shower, causing them to crash-land on Earth, now a desolate and uninhabited planet which humans had evacuated a thousand years earlier due to an environmental cataclysm. Cypher and Kitai survived the crash, but Cypher's legs are broken, and the main beacon for firing a distress signal is damaged. Cypher instructs Kitai to locate the tail section of the ship, which broke off on entry to the atmosphere. Inside is the backup beacon, which they can use to signal Nova Prime. Cypher gives Kitai his weaponized cutlass, a wrist communicator, and six capsules of a fluid that enhances oxygen intake so he can breathe. Kitai leaves to find the tail section, with Cypher guiding him through the communicator. Kitai confronts many hazards; bitten by a paralytic leech after fleeing from a pack of baboon-like monkeys, he self-medicates but damages two of his capsules. After awakening, Kitai takes shelter just as the thermal shift arrives, where Cypher tells him a story about how he conceived "ghosting" to kill the Ursas. Kitai reaches a cliffside waterfall, and Cypher learns about the broken capsules. Knowing that the only way to continue with two capsules would be to skydive, Cypher orders Kitai to abort the mission, but Kitai, believing that his father sees him as a disappointment, refuses to comply after blaming Cypher's absence at home for Senshi's death. Kitai disobeys Cypher's order and skydives down the waterfall but is captured by a large eagle, and his communicator is damaged. In the eagle's nest, Kitai fails to defend her chicks against large panthers before escaping to a river, where he drifts on a raft and a thermal shift nearly freezes him to death. The eagle, who had been following him, shelters Kitai, sacrificing her life. Kitai reaches the tail section and learns that the ship's Ursa has escaped and killed the rest of the crew. He tries to activate the emergency beacon, but the atmosphere blocks the signal. He climbs up the volcano where he hopes the high altitude will help to activate the beacon, but he encountered the loose Ursa, and it attacks him. Kitai kills it using the "ghost" technique he learned from Cypher. After activating the beacon, he and Cypher are sent back to Nova Prime via a rescue team.

In prehistoric times, a meteor crashed into Earth and killed all the dinosaurs. In the present day, industrialist John Greystoke funds an expedition to Uganda to locate the meteor and harness its energy. Aided by scientist James Porter, the expedition is a failure and John decides to leave with his wife and their son John Jr. While flying over a semi-active volcano, the Greystokes' helicopter's instruments go haywire. Forced to land on the meteor, John explores a cave and discovers glowing rock formations. Using his pickaxe, John collects a sample, only to cause a chain reaction that awakens the volcano. While trying to escape, their helicopter crashes, with only John Jr. surviving. The boy is discovered by the Mountain gorilla Kala, who recently lost her child. Adopted into the troop, John chooses to be called "Tarzan," a name he made up meaning "Ape with no fur." Tarzan grows up learning the ways of the animals. After the Greystokes' disappearance, Dr. James Porter funds his expeditions by acting as a jungle guide for wealthy tourists. During a routine safari, a client wanders away from the group, attracting the attention of a cassowary. Dr. Porter's daughter Jane saves him by putting herself in danger, as she is bitten by a viper. Infatuated with the girl, Tarzan carries Jane to a shelter and cures her. The next day, she returns to her father's camp with only vague memories of the night before. Confused by exposure to humans after so long, Tarzan decides to leave his gorilla family. He wanders to the site of the helicopter crash, finds the meteor stone his father took, and builds a shelter. Years later, Tublat, the apes' abusive leader, noses around Tarzan's shelter and accidentally activates the helicopter's emergency beacon. The transmission is received by Greystoke Energies. William Clayton, the current CEO, knowing what John senior was looking for, sees a chance to make money. He promises Jane, who now works for a conservation group, to fund her organization if she accompanies him to Africa to speak with her father. In Africa, Jane is disgusted by Clayton's greed. She leaves the party, wanders into the jungle, and finds Tarzan, now a man. Astounded, he brings her to his refuge. As a mark of love, Tarzan chips off a piece of the meteor rock and gives it to her. The rest of the group tracks Jane down there, where Clayton is shocked to find the Greystoke heir alive. Seeing him as a threat to his power, Clayton starts to shoot. The couple flees and is forced to enter a valley affected by the meteor, which causes unique mutations in the local flora and fauna, turning them into monsters. Surviving many dangers, the couple reaches the meteor, where Tarzan recognizes his father's long-abandoned pickaxe. Jane realizes Tarzan's true identity as John's son. Tarzan returns to his ape tribe, where he introduces Jane to Kala and challenges Tublat for the right to lead. In the ensuing fight, Tarzan defeats Tublat and exiles him from the troop. That night, Jane and Tarzan admit to their love. Meanwhile, Clayton transforms Dr. Porter's base into an armed base filled with mercenaries. A conflict later ensues between the couple and Clayton's men. Kala runs in to protect Tarzan and Jane, getting shot in the process. Tarzan is attacked from behind and locked in a cage. Aided by his gorilla friends, he escapes, moves Kala into the jungle, and treats her wound, determined to get his revenge. Clayton moves his resources to the meteor and rigs it with explosives. Tied up there and left to die, Jane and her father are rescued by Tarzan. Dr. Porter decides to stay behind and try to stop the blasting. In the ensuing battle, Tarzan summons his animal friends with a scream, the meteor awakens the volcano and the mountain begins to give way. While Clayton and his crew fall to their demise, Jane and Tarzan escape. The couple reunites with Tarzan's family and vows to protect the forest. Meanwhile, Dr. Porter climbs up the cliff where he has gotten a piece of the meteor.

Teenager Dallas Edwards and his derelict friends go on a quest for the meaning behind a series of mysterious, paranormal events in Southern California.

A small spaceship docks at a refuelling station, carrying four aliens: Bernard, Sandra, Desmond, and Julian. During a particularly tedious period at the station, Sandra, Desmond, and Julian begin playing with the ship's controls, while Bernard goes outside to play a game of spaceball. Their recklessness causes a malfunction that disconnects Bernard's part of the ship, leaving him stranded, while the other three crash-land on a nearby blue planet — Earth. The trio arrives in the United Kingdom, where their unusual appearance immediately draws attention. They are captured and interrogated in a secret government facility. Threatened with murder by a paranoid American colonel, they escape with the assistance of a hapless TV reporter, Graham Sweetley. Following their escape, they become instant celebrities, despite offering no technological knowledge or significant insight to humanity. Sweetley becomes their manager, organizing appearances and performances, and the aliens quickly achieve fame and wealth, entertaining audiences who are fascinated by their novelty rather than their abilities. Meanwhile, Bernard arrives on Earth separately, landing in the United States. Despite being the most intelligent of the group, he receives no recognition or celebrity. His claims of being an alien are dismissed, and he experiences homelessness and a brief stay in a mental hospital. Near the end of the film, Bernard reunites with his companions in the UK. Sandra, Desmond, and Julian, fearing that Bernard’s presence might diminish their fame, initially conceal that he had been traveling with them all along.
