The film opens with a family of tourists on the island of Isla Sorna. The young daughter explores on her own and runs into a baby Compsognathus. When the child attempts to feed the dinosaur, a large pack emerges and attacks the girl for more food. She is rescued by her parents and brought back to the mainland.
Four years have passed since the disaster at Jurassic Park, and John Hammond has lost control of InGen to his ruthless nephew, Peter Ludlow. Despite having signed a non-disclosure agreement about the prior events, chaos theorist Ian Malcolm has gone public and revealed details of his experiences at Jurassic Park. Unfortunately for him, his stories are not widely believed, threats of legal action prevent him from producing any evidence, and his academic reputation is destroyed.
Hammond summons Malcolm to his home, where he reveals the existence of Site B, Isla Sorna. Sorna was the facility where the dinosaurs were actually engineered, before being sent to Isla Nublar when mature. The island was abandoned after a hurricane wiped out most of the facilities, and the creatures have been living in the wild ever since. Hammond explains that the loss of Nublar and the incident with the girl have severely damaged InGen’s finances, and so Ludlow plans to bail the company out by exploiting Site B. Hammond requests Malcolm’s help in stopping Ludlow and preserving the dinosaurs’ natural habitat. He initially refuses, but after learning that his girlfriend, paleontologist Sarah Harding, is already on the island, he goes along.
Later, as Malcolm and Sarah fall asleep on the couch in their living room, Kelly is watching television and sees the cargo ship on its way back to Site B, surrounded by a convoy of naval vessels. The program breaks away to an interview of restored InGen Chairman John Hammond, who explains that the island will be left alone as a natural reserve so the dinosaurs can live free of human interference. He offers a quote by Malcolm, “Life will find a way.” The scene cuts to Site B, where the family of Tyrannosaurs is shown in the wild, alongside various other dinosaurs.
