It's four years later, and the chief creator of Jurassic Park sends an expedition of four people to check on "Site B", a secret place where the dinosaurs were developed and which now sports dinosaurs roaming free. The quartet is supposed to document the goings-on, but soon discover they will not be alone on the island, as the creator's nephew envisions Jurassic Parks across America and wants to capture some dinos to exploit for profit. Jeff Goldblum, Julianne Moore, and Vince Vaughn star. Directed by Steven Spielberg.
