Plot Summary

On Isla Nublar, a new park has just been built with genetically engineered dinosaurs. Tragedy strikes when one of the workers is killed by a velociraptor. The founder of the park, John Hammond, (Sir Richard Attenborough) requests Paleontologist Dr. Alan Grant (Sam Neill) and his assistant, Dr. Ellie Sattler (Laura Dern) to come to the park and ensure that it is safe. Also joining them are Hammond's lawyer Donald Gennaro (Martin Ferrero) and chaotician Dr. Ian Malcolm (Jeff Goldblum). When they reach the island, they are amazed to discover that Hammond has created living dinosaurs. However, at the same time, they all have their doubts. Later, Hammond's grandchildren Lex and Tim (Ariana Richards and Joseph Mazzello) join the group in a tour of the park. Sattler leaves the tour to take care of an ill triceratops. Soon the power in the park is shut down by computer systems geek Dennis Nedry (Wayne Knight), who wishes to steal embryos from the park to sell to a secret buyer. In the process, many dinosaurs escape their paddocks, including the deadly Tyrannosaurus Rex, who, during a thunderstorm, escapes his paddock and attacks the children, and eats Gennaro. Malcolm is injured and Grant and the children are then lost in the park. Meanwhile, Hammond, Sattler, and the rest of the operations team learn that Nedry (who in the meantime has been killed) has locked up the computer system to cover his tracks. They attempt to get power back in the park in order to escape the island. After shutting down the system, then restoring it, the group realizes that velociraptors are also on the loose, and are now on the hunt for the visitors.—ahmetkozan
