Millionaire John Hammond (Richard Attenborough) asks two dinosaur experts (Laura Dern and Sam Neill) to act as consultants on his entrepreneurial endeavor--an amusement park with DNA-cloned live dinosaurs as the main attraction. The paleontologists, along with a mathematician (Jeff Goldblum) and Hammond's two grandchildren, takes a run-through tour of the park. But soon the joyride turns to terror when an impending hurricane, an unscrupulous engineer (Wayne Knight), and the rebelling dinosaurs begin to destroy the park.
