Ben Hildebrand (Mark Harelik) and Eric Kirby (Trevor Morgan) go parasailing over the waters near Isla Sorna, 207 miles west of Costa Rica. The boat's crew disappears, and the top of the boat is destroyed, prompting Ben to detach the line before the boat crashes. He and Eric drift towards the island. Eight weeks later, paleontologist Dr. Alan Grant (Sam Neill) has made a new discovery about the intelligence of Velociraptors but struggles to secure funding for his research. Grant discusses his discovery of a resonating larynx on fossilized raptor remains with his longtime colleague Ellie (Laura Dern). Ellie is now married with a husband Mark and 2 kids. Mark (Taylor Nichols) works for the state department, specializing in international treaty law. Grant says that the larynx of the raptors was a tremendous evolutionary advantage. This, and his experience at Jurassic Park, leads him to believe that the original Velociraptors were socially sophisticated, and smarter than dolphins, whales and even primates. They were able to hunt in numbers and coordinate their attacks. He hypothesizes that if they had not gone extinct and continued to evolve, their descendants-rather than humans-would have become Earth's dominant species. At a symposium, Grant declares that all John Hammond and Ingen did at Jurassic Park was to create genetically engineered theme park monsters. He says that he has no intention of visiting Isla Sorna. His assistant Billy Brennan (Alessandro Nivola) uses a 3D printer to replicate the Velociraptor larynx. Grant laments that he would have to wrap up his field research in 4 weeks if additional funding is not approved. Paul (William H. Macy) and Amanda Kirby (Téa Leoni), posing as a wealthy couple, offer funding for Grant's research if he will give them an aerial tour of Isla Sorna, claiming they have permission to fly over the island. The Kirbys say that they are adventurers and have been to the Nile, the K2 and the Galapagos. They even claim to have 2 seats on the first commercial flight to the moon. Paul offers a big check to Grant to help him to agree. Grant reluctantly agrees and flies there with Paul, Amanda, Billy, and the Kirbys' mercenary associates Udesky (Michael Jeter), Cooper (John Diehl), and their pilot Nash (Bruce A. Young). During the flight, Grant learns that the Kirbys plan to land on the island; he protests but Cooper knocks him unconscious. Grant awakens to discover that they have landed. Grant is adamant that the island is not safe, even as Amanda calls out for Eric using a loudspeaker. A Spinosaurus approaches the group, who board the plane to escape, leaving Cooper behind as he tries to reach the plane. The Spinosaurus emerges on the runway and devours Cooper. In avoiding the Spinosaurus, the plane clips the dinosaur and crashes into the forest. The Spinosaurus destroys the plane and consumes Nash, who had possession of Paul's satellite phone. Fleeing, the survivors briefly lose the Spinosaurus but encounter a Tyrannosaurus Rex. The Spinosaurus returns and the group escapes while the two dinosaurs engage in a battle, with the Spinosaurus killing the Tyrannosaurus. Grant furiously confronts the Kirbys, and learns that the Kirbys are a middle-class, divorced couple who are looking for their son Eric and Amanda's boyfriend Ben, who went missing on the island. Government agencies declined to help the Kirbys, so they brought Grant along as an expert because of his past experience at Jurassic Park. To their dismay however, Grant explains his previous visit was to Isla Nublar, not Isla Sorna, and as such is just as lost as they are. The group searches for Eric and Ben as they travel to the coast. They find Ben's corpse attached to the para-sail, which Billy takes. They also stumble upon Velociraptor nests, and Billy secretly steals two eggs in his bag. The group find an abandoned InGen compound. A raptor chases them and summons the rest of its pack. The humans flee into a herd of Corythosaurus and Parasaurolophus, causing a stampede, and separating Grant and Udesky from the others. The raptors attack Udesky in an attempt to lure the others out of a tree and almost succeed in attacking Amanda when she tries to descend to help him. The raptors' trap fails, and they kill Udesky before departing. Elsewhere, Grant observes the pack communicating and suspects that they are searching for something; as he tries to slip away, they ambush him. Eric appears, dispersing the attack with tear gas, before taking Grant to an overturned supply truck where he has been taking shelter. The next day, Grant and Eric are reunited with Billy and the Kirbys. The group is then chased by the Spinosaurus but manage to lock it out by entering an abandoned observatory. Grant finds the Velociraptor eggs in Billy's bag, which provoked the earlier attacks. Billy hoped to sell the eggs to fund their dig site. Grant disapproves of this idea, but keeps the eggs regardless, hoping the Velociraptors may spare the group if they are returned. The group unknowingly enters a large aviary used to house Pteranodons, which attack the group and fly away with Eric. Billy rescues Eric using Ben's para-sail but is then attacked and seemingly killed by the Pteranodons. The rest of the group escapes the aviary, unknowingly leaving the door unlocked. They find a boat and make their way down a river. That night, the group retrieves the ringing satellite phone from the feces of the Spinosaurus. Grant contacts Ellie and tells her where they are but the Spinosaurus attacks the boat. Grant ignites the boat's fuel, causing the Spinosaurus to flee. The next morning, the group makes its way towards the coast but are surrounded by the raptors. They surrender the eggs to the raptors while Grant uses the replica raptor larynx to confuse the pack, which runs off with the eggs. The group reach the coast and see that Ellie had called in the Marine Corps and the Navy to rescue them. They discover that Billy, while seriously injured, has also been rescued. As they leave the island, they see the Pteranodons fly by.

John Hammond opens a theme park with cloned dinosaurs, but things go wrong when a sudden power failure occurs and a group of visitors fight for survival as the dinosaurs run amok.
