Tommy Spinelli is a wiseguy hired by Benny and Rico, a pair of dimwitted hitmen, to transport a duffel bag full of severed heads across the United States to crime boss "Big Sep" (as proof of the deaths). While on a commercial flight, his bag is accidentally switched with that of Charlie Pritchett, a friendly, talkative, young American tourist who is going to Mexico to see his girlfriend Laurie and her parents, Dick and Annette. Spinelli harasses Charlie's friends Ernie and Steve for information, while Charlie and Laurie attempt to get rid of their rather unfortunate luggage. After Charlie meets with Laurie and her parents at the airport with the wrong bag, they go to their rooms at the resort in Acapulco, Mexico. Soon, Annette mistakenly thinks that Charlie might be a serial killer on the run once she sees a head in his bag while hiding a gift for him inside the bag. Her husband thinks it's all a delusion brought on by her alcoholism. At first, Charlie and Laurie try to bury the heads in the desert, but a group of thugs steals their car. Then Charlie comes up with an idea that he will give back the heads without anyone noticing, by pretending he forgot to turn in his report back at his college. In turn, everyone packs up for the airport.At the airport, Charlie accidentally puts a severed head in Dick's carry-on bag, causing him to get arrested. They never leave Acapulco since they have to come up with a new plan to save Dick. Meanwhile, Tommy, Ernie and Steve start to look for replacement heads, after Charlie tells Tommy he lost one. They start to look in a cryonics lab, where they store bodies and severed heads, much to Tommy's approval. After getting the replacement heads, Tommy and the others get on a plane and head to Mexico. Tommy threatens Charlie that if he loses more heads, he'll replace them with Charlie's friends and family. After hearing of the airport incident, Benny and Rico decide to collect the heads for themselves. When Fern, Dick's mother, arrives in Mexico, Tommy takes her and the others hostage as he helps Charlie find more heads. They find out that a coyote took one of the heads from the stolen car. Tommy also realizes that Benny and Rico are going to kill him if he doesn't get the heads across the border in time. Charlie comes up with a plan to save both their lives. Charlie and Laurie take a severed head to the airport to prove her father's innocence. Benny and Rico try to intervene, but end up getting arrested. It is revealed that Tommy and Charlie set them up. Charlie thanks him for his help, as Tommy departs to Hawaii. Steve goes insane and starts running around the airport with a severed head, telling security guards that it is his "best friend". Charlie and Laurie get married, with her mother and father present; Steve is in a straitjacket; Ernie is a brain surgeon; Fern is also present in a full body cast after being thrown out of a moving van when she started to bad-mouth Tommy; and Tommy is enjoying his retirement.

At a corporation's base on the Neptunian moon Triton, mercenaries are setting up a defense perimeter to try to hold off an unstoppable cyborg warrior. The company's CEO E.J. Saggs and chief scientist Dr. Nabel seal themselves inside the control room. The cyborg destroys the soldiers' tank and then attacks a helicopter, which crashes into the control room. The soldiers are killed one by one, until Nabel finally deactivates the cyborg with a remote control. The remaining corporate employees discover that the cyborg was created by Nabel for the company. Saggs takes the remote and reactivates the cyborg, ordering it to kill Nabel. Meanwhile, John Canyon, one of the last independent "space truckers", drops off his cargo of square pigs at a "truck stop" space station, but becomes embroiled in a brawl with the trucking company head, Keller, who is sucked out into space. He and his two passengers—Cindy, a waitress who has promised to marry him in exchange for a ride to Earth to see her mother, and Mike, an up-and-coming trucker working for the company—take on a deal to transport alleged sex dolls to Earth. Chased by police investigating Keller's death, John takes his rig into the "scum cluster", a region controlled by pirates. The rig takes damage, leaving them adrift; they are soon captured by the pirate ship Regalia, commanded by the company-hating Captain Macanudo. Cindy agrees to have sex with him if he would take the cargo and let them go. The captain is revealed to be Nabel, who rebuilt his grievously injured body and went into piracy as revenge against Saggs for betraying him. The cargo that John's rig is carrying is in fact a full supply of the cyborg warriors Nabel designed and built for Saggs' company. One of the cyborgs activates, kills most of the crew, and severely damages the ship. John, Cindy and Mike take their rig and escape as the Regalia explodes. As they make their way back to Earth, John and Mike find a mortally wounded Macanudo in the hold, who reveals the true nature of the cargo to them. John releases Cindy from any obligation of marrying him, and tells her and Mike to take the escape pod while he releases the cargo in the atmosphere, where it will burn up on re-entry. Cindy and Mike land safely, but the rig is unable to return to space and explodes in the sky; however, John is able to safely escape before the explosion. John, Cindy and Mike go to the hospital to see Cindy's mother, who became sick twenty years earlier and was frozen until a cure was found; John is smitten with her at first sight. Meanwhile, Saggs—now President of Earth after the government was privatized—visits John, Cindy and Mike in the hospital, where he offers John a new rig and gives the trio a suitcase full of money to keep them quiet about his cyborg invasion plan. John tactfully agrees to the deal, convinced they will all be assassinated if they don't accept, but Mike angrily throws the suitcase out the window. Below, Saggs re-enters his presidential limousine; having planted a bomb in the suitcase, he triggers the detonator just as the suitcase lands on his limousine's roof, killing him. With Saggs dead and Earth safe, but also having inadvertently blown up the president, Mike, Cindy, John and Cindy's mother quietly escape to the spaceport and blast off in their brand new rig.

Extreme sport athlete Johnny Utah and his friend Jeff are traversing a steep ridgeline on motorbikes. The run ends with a jump onto a lone stone column, where Jeff overshoots the landing and falls to his death. Seven years later, Utah is an FBI agent candidate. He attends a briefing on a skyscraper heist in Mumbai, in which the criminals stole diamonds, escaping by parachute. A similar heist happens in Mexico where the criminals unload millions of dollars in bills, then disappear into the Cave of Swallows. Utah's research concludes that they were done by the same men, who are attempting to complete the Ozaki 8, a list of eight extreme ordeals to honor the forces of nature. They have already completed three, and Utah predicts they'll attempt the fourth on a rare sea wave phenomenon in France. After presenting his analysis, Utah is sent undercover to France under a field agent named Pappas. They reach France and Utah gets help from others to surf the tall tube wave. As he goes in, there is already another surfer riding the wave, leaving Utah unstable. Utah gets sucked into the wave and faints, but the other surfer bails and rescues Utah. He wakes aboard a yacht with the surfer, Bodhi, and his team: Roach, Chowder, and Grommet. They leave him to enjoy the party and he gets acquainted with a girl, Samsara. The next day, Utah finds the men in an abandoned Paris train station after he overhears them talking about the location. Bodhi gives him an initiation fight and soon he is accepted into the circle. They travel to the Alps for the next ordeal: wingsuit flying through "The Life of Wind" cliffs. The four succeed in their attempt and spend some time together with Samsara. The next day, they climb the snow peaks for the sixth ordeal, snowboarding down a steep mountain of snow. They reach their spot, but Utah decides to extend his line, so the others follow him. Chowder slips and falls to his death, and Utah becomes depressed about it. After a party, Samsara explains that she and Bodhi both knew Ono Ozaki when they were young, that her parents died in an avalanche accident and Ozaki gave her a home after. She explains further that after Ozaki completed his third ordeal, despite what was widely believed that he died attempting the ordeal, he was actually killed by a whaling ship crashing into his boat while he was trying to save humpback whales. On his boat, Bodhi (a young boy at the time) decided not to tell the truth of his story but to finish what Ozaki started. Next they travel to a gold mine where Bodhi detonates explosives Grommet and Roach planted. After blowing his cover, Utah chases Bodhi, managing to trip his bike. Bodhi escapes because Utah cannot stand up after the crash. The FBI freezes Bodhi's sponsors' assets; Bodhi plans to rob a nearby Italian bank on a mountain top. Utah and the police intercept the group, resulting in a crossfire that kills Roach. As the group flees, Utah chases and shoots one of them to death, who is revealed to be Samsara and not Bodhi. Utah finds the location of the next ordeal: free solo climbing with no safety beside Angel Falls in Venezuela. He finds Bodhi and Grommet and chases them on the climb, but Grommet falters, falling to his death. Utah catches up to Bodhi, but he falls backward down the waterfall, completing what should have been the last ordeal. Bodhi, however, has to redo the fourth ordeal, because he bailed out on the wave when he chose to save Johnny. Seventeen months later, Utah finds him in the Pacific facing another giant wave. As Utah tries to get Bodhi to come back with him and pay for his crimes, he eventually lets Bodhi attempt to surf it, both knowing that he will not come back. The wave engulfs Bodhi, killing him. Utah begins going through his own ordeals, unclear whether he is still an FBI agent.

In the aftermath of a financial crisis in the European Union and the weakening of NATO, collaborative dealings have occurred between a progressively militant North Korea and an ultranationalist Russia. The American mainland has become largely undefended from the increased deployment of U.S. troops abroad, and American infrastructure is increasingly vulnerable to cyberattacks. U.S. Marine Jed Eckert is on home leave in Spokane, Washington, where he reunites with his father, Spokane Police Sergeant Tom Eckert, his brother, Matt Eckert, and his childhood friend Toni Walsh and her cousin Erica Martin, Matt's girlfriend. Matt, the quarterback for his football team, blew a playoff game because of his cowboy antics. After the city suffers a blackout, Jed and Matt witness North Korean paratroopers and transport aircraft invading the town. Their father tells them to escape to their cabin in the woods while he helps the townspeople. They're joined by Matt's friends Robert Kitner, Daryl Jenkins, Danny Jackson, siblings Julie and Greg Goodyear, a stranger named Pete, and his buddy. After Erica is captured, Toni joins them as well. As the group debates whether to surrender or resist, Pete and his buddy steal their supplies, inadvertently betraying their position. Captain Cho and his soldiers order Daryl's father, the mayor, to convince the group to surrender. Sergeant Eckert refuses to cooperate and is executed by Cho after encouraging them to resist, and the cabin is then torched to the ground. Jed is determined to fight back, and the group joins him. Under Jed's training, the group learns to hunt for survival, use weapons, and establish a base in an abandoned mine. The group, naming themselves the Wolverines after their school mascot, stage guerrilla attacks on soldiers and collaborators, including Pete, who is killed in a bombing. During a plot to eliminate the leadership during a rally, Jed soon finds Russian Spetsnaz working with the North Korean army. However, Cho discovers their bomb, compromising their mission. Matt recklessly strays from the plan to free Erica, who was on a prison transport, but Greg is killed in the process. The North Koreans find their location and retaliate with artillery fire, destroying their base, and killing Danny and Julie. The surviving Wolverines later encounter U.S. Marines Sergeant Major Andrew Tanner, Corporal Smith, and Sergeant Hodges, who reveal that a Russian-backed North Korean forces used a EMP weapon to disable the U.S. electrical grid and crippled the military forces, immediately followed by landings along the east and west coasts. American counterattacks eventually halted their advances, leaving a large area stretching from the Rocky Mountains to the Appalachians as "Free America" while pockets of resistance continue to oppose the invasion. The Wolverines learn that Captain Cho's suitcase contains an EMP-resistant radiotelephone, and if they can steal it, the U.S. command could use it to their advantage in a counter-offensive. The Wolverines help the Marines infiltrate the police department, which is being used as the North Koreans' operation center, and steal the suitcase. Jed kills Cho, though Hodges is killed in the firefight. The Wolverines and Marines regroup at a safe house with the suitcase, but Jed is killed in an ambush by Russian Spetsnaz. As Matt and the group escape with the suitcase, Robert discovers that Daryl was tagged by the Russians with a subcutaneous tracking device during the police station raid. Knowing he cannot go with them, Daryl stays behind to buy time for the others as they head to the Marines' extraction point. Tanner and Smith depart with the suitcase, while the remaining Wolverines stay to continue fighting under Matt's leadership.

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.

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".

Astérix and Obélix must win the Olympic Games in Greece in order to help their friend Lovesix marry Greek princess Irina. Brutus uses every trick in the book to have his own team win the game and get rid of his father Julius Caesar in the process. The film is loosely adapted from the original Asterix at the Olympic Games comic book. The love story subplot between Lovesix and Irina was not featured in the original story. Brutus, portrayed here as a comical villain with no relation to his depictions in Asterix comics, is the main antagonist, although he was not even featured as a character in the original comic book.

While hosting a party in his Manhattan penthouse, financial publisher Chris Thorne meets beautiful lawyer Diane Lightson, and agrees to escort her to consult client Howard Suntz in Atlantic City the following day. Two of Chris's clients, boisterous Brazilian billionaire siblings Fausto and Renalda Squiriniszu, overhear Chris planning the road trip with Diane and invite themselves along. During the trip, the Squiriniszus urge Chris to take a scenic detour off the drab New Jersey Turnpike, which ultimately places them in the dilapidated village of Valkenvania. After running a stop sign and subsequently attempting to outrun pursuing chief of police Dennis Valkenheiser, the group is captured and taken before his 106-year-old grandfather, Judge Alvin "J.P." Valkenheiser. At their hearing, Chris's dismissive and disrespectful attitude offends Judge Valkenheiser, and the yuppies are locked in a hidden room under the courthouse to be judged the next day. They later overhear Judge Valkenheiser mercilessly executing a group of convicted drug dealers in a deadly roller coaster nicknamed "Mr. Bonestripper". Invited upstairs for dinner, the quartet learns that Judge Valkenheiser is detaining them due to his deep and longstanding grudge against "bankers", which he considers Chris to be. Judge Valkenheiser explains that in 1917, a financier from New York swindled his grandfather into mining out the town in exchange for shares in the now defunct United Coke Company, subsequently impoverishing both the family and the town. The group attempts an escape, but Judge Valkenheiser's massive mute granddaughter Eldona captures Chris and Diane. The Squiriniszus escape by jumping through a window, and make it to the edge of the property before encountering a waiting Dennis. Noticing that Dennis seems stressed and overworked, the Squiriniszus talk him into abandoning his dead-end life and career by escaping with them. A series of trick hallways and booby traps land Chris and Diane in an attic room filled with IDs and news clippings, where the couple discover that Judge Valkenheiser has been using the house to capture and terminate undesirables—especially bankers—since the 1890s. During another escape down a series of slides, Diane lands in the property's salvage yard, where she meets and befriends Judge Valkenheiser's severely deformed grandchildren Bobo and L'il Debbull, who are barred from living in the house. Chris, still in the house, sneaks into Judge Valkenheiser's bedroom to explore, but Judge Valkenheiser discovers and attacks him. While attempting to flee from Judge Valkenheiser, Chris collides with Eldona. Judge Valkenheiser ceases his attack and declares Chris must marry Eldona per "house policy". Meanwhile, in the court room, the alternative rap group Digital Underground, having been arrested for speeding, is ordered by Judge Valkenheiser to verify their claim of being musicians, which they do with an impromptu performance. Delighted, Judge Valkenheiser acquits the band, but then asks them to stay behind as musicians and witnesses for the wedding. Chris initially cooperates in exchange for his life, but is later caught pleading with the group to help him escape. The band departs without understanding Chris's plight, and an enraged Judge Valkenheiser sentences him to execution via "Mr. Bonestripper". The machine breaks down just before Chris is fed into it, and he escapes unscathed into the junkyard. Judge Valkenheiser attempts to lure Chris by abducting and trapping Diane in another murderous contraption known as the Gradertine, but Chris distracts the Valkenheisers by setting off an explosion, proceeding to retrieve Diane at the last second before the pair escapes the premises via a passing freight train. After Chris and Diane report their ordeal to the authorities, the police prepare a large-scale raid of Judge Valkenheiser's courthouse. Chris and Diane are asked to accompany the police to Valkenvania only to discover that the troopers involved are fully aware of and allied with Judge Valkenheiser due to his ability to swiftly handle undesirables. Just as the combined forces are about to dispatch Chris and Diane for knowing too much, the massive underground coal fires roar out of control, finally destroying the courthouse, and the duo successfully escapes from the ensuing chaos. In Brazil, Dennis, now the Squiriniszus' personal security detail and Renalda's lover, vows to shield the siblings from harm. Back in New York, Diane awakens Chris to the news broadcast of the Valkenvania disaster. Chris spots Judge Valkenheiser rummaging through the debris where he announces that he and the rest of his family survived. Brandishing Chris's driver's license, Judge Valkenheiser announces that they plan to move in with "grandson" Chris, who panickily flees the scene, leaving a cartoonish hole in the wall.

Bull is a two-year-old mutt from Chicago who frequently humps anything that piques his interest to vent his perverse instincts. He is friends with Rocco, a proud, British-accented boxer; Fetch, a wannabe-influencer dachshund; and Lucky, a dim-witted, masochistic Jack Russell, all of whom except for Bull have been neutered, which makes them a target of ridicule from the haughty, self-absorbed Borzoi show dog Sterling. Bull also harbors a crush on his neighbour, another show dog Borzoi named Honey, but is hesitant to reveal his true feelings for her. One day, Bull's owners throw him a party where they pamper him with treats and toys. But when Bull gets to the Kool-Aid-flavored toilet water, he realizes that this means he is due to be neutered the following morning, as Luther, a Great Dane, had a similar pre-neutered experience. Bull bemoans his experience, alienates his friends as they attempt to comfort him and decides to leave home in order to save himself from being sterilized. However, he soon reconsiders when he is accosted by a large clowder of alley cats, but is rescued by his friends, who came searching for him when he ran away from his home. Reconciling, Bull and his friends barely manage to escape the cats' territory. As Bull decides to return home and face his impending neutering, Rocco convinces him to have one last wild night on the town to make sure his last night of being intact will be one to remember. The foursome get into various shenanigans, such as infiltrating a dog show that Honey is competing in alongside Sterling. Bull finally musters the courage to share his attraction to her with her until she and Sterling win, causing him to sadly leave. The group soon visits "The Humphouse", a dog-friendly version of a strip club, where Lucky falls for the intersex Dobermann bouncer, Frankie. Meanwhile, Bull is seduced by Molasses, an attractive red Borzoi who reminds him of Honey. Molasses gets Bull to knot her, just as Honey, who abandoned the dog show for Bull, stumbles upon the scene and angrily confronts him. Soon, Bull, Honey and the others are captured by animal control and taken to the dog pound, where Honey is eventually released as her owners are informed whereabouts via a chipped in her fur. Realizing that Honey and Sterling will breed due to them winning the dog show, Bull and his friends escape the pound and venture to Bull's house, though Lucky deviates from the group to reunite with Frankie. Bull manages to physically intervene between Honey and Sterling as they're about to breed. However, an oblivious Sterling unknowingly sodomizes Bull, believing to be breeding with Honey. Bull confesses his feelings for her, apologizes and then leaves. Later at night, after Bull reunites with his family, Honey lures him into a backyard treehouse, where she confesses her love for him and the pair then mate. Inevitably, Bull is neutered, but not before he becomes the father of his and Honey's litter of thirteen puppies three months later. Meanwhile, Sterling discovers that he will also be neutered, much to his horror, as Luther mocks him. Later on, Honey and her own pack of friends visit The Humphouse to watch a grizzly bear twerk, to the delight of the audience and to Bull, Rocco, Fetch and Lucky's astonishment.

Roman-Catholic priest Doug Jones witnesses his parents die in a VFX car fire. He travels to China on a spiritual journey and comes across ninjas searching for an artifact said to turn people into the "Dragon Warrior". After becoming infected by the artifact, Doug begins having nightmares and he gets a kiss from his mentor Father Stewart. Doug then goes out into the forest late at night as he transforms into a dinosaur. He saves Carol, a prostitute, from a thug. Waking up in Carol's bed naked, with no memory of the night before, Doug initially believes they had sex, but after Carol tells him what happened he realizes the truth. Unpersuaded by her suggestion to use his new power to fight crime and get rid of people they believe are beyond spiritual salvation, he returns to the church for confession; speaking to Frankie Mermaid, Carol's pimp, he learns Frankie is the one responsible for killing Doug's parents. Enraged, Doug proceeds to kill Frankie and, now convinced about her plan to fight crime, returns to Carol needing her assistance. Father Stewart, learning of Doug's new power, encourages Doug to lose it and stop killing. He takes him to see Altair, an exorcist, hoping to remove Doug's power. In a flashback, it is revealed that Father Stewart saw a war buddy shot while off guard and that his love interest was killed by a mine. In the present, the exorcism fails and Doug transforms, slashing one of Father Stewart's eyes. Returning to Carol, Doug is confronted by ninjas. Father Stewart wakes up in a camp of drug-dealing Christian ninjas led by Wei Chan, who plans to sell highly addictive cocaine to people and then cut off supplies. Wei Chan hopes this will lead the addicts to turn to the church, where he will eventually take over, and use them as his army. Father Stewart rejects this idea, and is killed. Doug and Carol are confronted by ninjas, and plan to stop Wei Chan. Doug is stopped by Sam, the White Ninja, who he later realizes is his brother. Doug catches Sam off guard and uses telekinesis to take Sam's sword and kill him. Doug and Carol fight off more ninjas, and the latter is badly wounded. Doug, transforming into a velociraptor and fighting off the remaining ninjas, is shot by Wei Chan with an arrow containing venom to stop his transformation. Doug's hands are immune to the venom, and he proceeds to kill Wei Chan using his dinosaur powers, among other techniques. Doug carries Carol to the hospital where she recovers. Doug, no longer a priest and with a billion-dollar bounty on his head, plans to travel the world with Carol, and continue their original plan to kill off criminals.

During an expedition into Central Africa, paleontologist Dr. Susan Matthews-Loomis and her husband George Loomis attempt to track down evidence of a local monster legend. The monster, which the local natives refer to as " Mokele-mbembe ", shares many characteristics with the Sauropod order of dinosaurs. During the expedition, they discover brontosaurus in the deep jungle and are further amazed when the animals show very little fear of them. The couple begins observing the creatures and become especially enamored with the curious young offspring of the pair, whom they nickname "Baby". Unfortunately, the discovery soon places the dinosaurs in jeopardy from both the local military as well as fellow scientist Dr. Eric Kiviat. Whereas Dr. Kiviat sees Baby and his parents as his ticket to fame and fortune, the African military led by Colonel Nsogbu sees the dinosaurs as a threat and makes several attempts to destroy them. During one such attempt, the adult male brontosaurus is killed and the adult female captured. The Loomises are able to escape with Baby, but quickly find themselves lost in the jungle while being pursued by Colonel Nsogbu's forces. After finally escaping their pursuers, the pair decide to circle back and rescue the female adult brontosaurus, whom Dr. Kiviat has persuaded Colonel Nsogbu to transport back to civilization. With the aid of the local tribe – who see Baby and his parents as legends – George and Susan are able to break into the military compound and release the mother brontosaurus. During the escape, both Kiviat and Nsogbu are killed. Afterwards, the Loomises take the pair to a secluded jungle lagoon and say a tearful goodbye to Baby as he follows his mother away into the deeper parts of the jungle.

Kenneth Zevo, the eccentric owner of Zevo Toys in Moscow, Idaho, faces terminal illness. Defying expectations, he bypasses his son, Leslie—a whimsical toymaker apprenticed at the factory—and appoints his estranged brother, U.S. Army Lieutenant General Leland Zevo, as successor. Kenneth believes Leslie's childlike nature would endanger the company, despite his talent. To aid Leslie's maturity, Kenneth hires Gwen Tyler, hoping they will form a romantic relationship. After Kenneth's death, Leland reluctantly assumes control but delegates factory operations to Leslie and his sister, Alsatia, due to their expertise. However, Leland's militaristic instincts surface upon learning of potential corporate espionage. He enlists his son Patrick, a covert operations specialist, to overhaul security. Inspired by war machinery, Leland proposes manufacturing military toys, clashing with Leslie, who cites Kenneth's pacifist ethos as company policy. Meanwhile, Leslie and Gwen begin dating. Secretly, Leland converts a factory section to develop miniature remote-controlled war machines, misleading Leslie by claiming it is for experimental toys. After the military rejects his prototypes, Leland grows unhinged, expanding production, militarizing the facility, and displacing workers—including Alsatia. Suspicious, Leslie and Alsatia infiltrate the restricted area and discover children piloting war drones via arcade-style consoles. They narrowly escape an amphibious drone, the "Sea Swine," and alert Gwen and Kenneth's former assistant Owen Owens. Patrick, learning Leland lied about his mother Dee Dee's death, defects to Leslie's side. The group infiltrates the factory, evading Leland's deadly toys, including "Tommy Tanks" and "Hurly-Burly Helicopters." Leslie rallies vintage Zevo toys from storage, unleashing them against Leland's army in a chaotic showdown. During the clash, Leland's helicopter misfires, destroying his control panel and deactivating his machines. A critical revelation emerges: Alsatia is an advanced robot built by Kenneth to be Leslie's companion after his mother's death. She is damaged defending against the Sea Swine but later repaired. Leland, attacked by his own drone, is hospitalized. Leslie assumes leadership, restoring the factory's playful ethos with Gwen, while Patrick departs for new missions. The film concludes with the group honoring Kenneth's legacy at a memorial.
