Malcolm initially refuses, but changes his mind when he learns his girlfriend, paleontologist (Julianne Moore), is already on Isla Sorna. He joins the team, which includes engineer Eddie Carr (Richard Schiff) and documentarian Nick Van Owen (Vince Vaughn). They arrive on the island.

The male T. rex escapes and rampages through the city: eating a dog, drinking from a swimming pool, smashing cars, and destroying a video store. Malcolm, Sarah, and Ludlow track it.

Ludlow, having survived, captures the adult male T. rex and takes the injured baby to a ship, planning to open an attraction in San Diego. But on the voyage, the crew is killed (implied by the raptors that were also aboard). The ship crashes into a pier in San Diego.

That night, Nick and Sarah secretly release the captured dinosaurs from Ludlow’s camp. The chaos attracts the adult T. rexes, who destroy the camp, kill several hunters, and eat Ludlow’s right-hand man, Dieter Stark. In the confusion, the injured baby T. rex (kept in a trailer) is brought to Malcolm’s trailer for treatment.
