The Lost World: Jurassic Park - Plot

Plot

Four years after the incident at Jurassic Park, a wealthy couple and their daughter hold a picnic on Isla Sorna. The girl wanders off and is attacked by a pack of Compsognathus before being rescued by her father and his servants.

Ian Malcolm publicized the incident at Jurassic Park, but disbelief has destroyed his academic reputation, and legal action has prevented him from getting any evidence. John Hammond, having lost control of InGen to his unscrupulous nephew, Peter Ludlow, and as a result of the family's accident, summons Ian to his home and tells him about Isla Sorna. Isla Sorna, also known as "Site B", is the island where the dinosaurs were engineered and nurtured for a few months, before being moved to Isla Nublar, the park's location. He explains that after Jurassic Park was shut down, a hurricane destroyed the containment facilities on Isla Sorna, and the dinosaurs have been living free in the wild ever since. Hammond asks Malcolm to join a team that will travel to Site B to document the dinosaurs in their natural habitat to rally public support and prevent Ludlow from exploiting the site for InGen and leave it as a nature preserve. Ian initially refuses, but agrees after learning that his girlfriend, paleontologist Sarah Harding, is part of the team and is already there, while the others will meet her after three days.

Ian meets the team of people he will join with: equipment specialist and engineer Eddie Carr, and documentary producer Nick Van Owen. Shortly after arriving on the island, they find Sarah and discover that Ian's adopted daughter, Kelly, has stowed away on the trailer. Ian tries to get Kelly home, but they're interrupted by the arrival of an InGen team of mercenaries, hunters, and paleontologists led by Ludlow, which they spot chasing and capturing several dinosaur species such as Parasaurolophus, Pachycephalosaurus, Gallimimus and Mamenchisaurus, for another park in San Diego. Tracker Roland Tembo wishes to hunt and kill an adult male Tyrannosaurus by luring it to the cries of its injured offspring. That night, Nick and Sarah sneak into the InGen camp to free the dinosaurs, which causes a huge commotion as a Triceratops destroys the camp and the dinosaurs escape.

During the commotion, Nick frees the baby Tyrannosaurus and takes it to the trailer so Sarah can set its broken leg. Ian takes Kelly to the high hide, a lift Eddie built to keep them safe above the trees. Ian, after trying and failing to contact the trailer via phone, returns on foot. Shortly after he arrives, two adult Tyrannosaurs find the trailer. The team gives the infant back, but the two adults begin pushing the trailer over the cliff with the team inside. Eddie leaves Kelly in the "high hide" and returns to the trailer in one of the SUVs. With the adults temporarily gone, Eddie is able to tie a rope to a tree trunk and send it down to Ian, Sarah, and Nick to grab onto. Eddie then ties a cable to the trailer to pull it back over the edge. He partially succeeds, but is attacked and eaten when the Tyrannosaurs return. The trailer and the SUV fall off the cliff, but Ian, Sarah, and Nick are rescued by the InGen team. With both groups' communications equipment destroyed in the attacks, they team up to reach the old InGen compound's radio station.

Roland's deputy Dieter Stark is attacked and killed by a pack of Compsognathus, His friend Carter fails to hear his screams because he was listening to headphones. At night, the Tyrannosaurs come across the group's camp and one of them pokes its head in Sarah and Kelly's tent while they hide under their sleeping bags but Carter sees the dinosaur and screams which makes everyone run. Carter falls and is crushed by the T. rex's foot. As everyone flees from the female, Roland stays behind and twice manages to tranquilize the male. Everyone hides in a waterfall and the T. rex licks them but Burke runs scared because a milk snake crawled in his shirt and the T. rex bites and pulls him out of the waterfall. Many of the team, including Roland's hunting partner, Ajay Sidhu, pass through a field of tall grass near the compound, but are killed by Velociraptors. Shortly after, Nick, having found Ajay's bag with the coordinates, splits off from the group to reach the compound and radio for help. Ian, Sarah and Kelly run for the compound, pursued by three raptors. After escaping from the raptors, they reunite with Nick and fly away in a rescue helicopter. While flying away, they spot the caged adult Tyrannosaurus and Ludlow preparing to ship it and its baby back to the mainland.

A cargo ship carries the Tyrannosaurus back to the mainland, but, upon reaching San Diego, crashes into the dock. Ludlow and several guards investigate the boat and find the crew dead. A guard opens the cargo hold, thinking there might be some crew members below, inadvertently releasing the Tyrannosaurus, which escapes into the city. Realizing that the creature will likely come for its infant, Ian and Sarah learn from Ludlow that the infant is already at the park. They rush to the park to get the baby and use it to lure the adult back to the boat. Ludlow tries to intervene, but is trapped in the cargo hold and he tries to ambush the infant but the adult appears and Ludlow runs up the stairs but the adult drags him down. Then the infant leaps on him and kills him while the adult looks. Ian and Sarah manage to tranquilize the adult before it can escape again and seal it in the hold.

The next day, Ian, Sarah and Kelly watch television reports of the cargo ship on its way back to Isla Sorna, surrounded by a convoy of naval vessels. During the program, they see an interview with Hammond, who explains that the American and Costa Rican governments have agreed to declare the island a nature preserve so the dinosaurs can live free of human interference, and adds "Life will find a way," paraphrasing something Malcolm told him on Isla Nublar four years earlier.
