The film is set on the fictional island of Isla Nublar, off Central America's Pacific Coast near Costa Rica, where a wealthy businessman John Hammond (Attenborough), and a team of genetic scientists have created a wildlife park of de-extinct dinosaurs.
When industrial sabotage leads to a catastrophic shutdown of the park's power facilities and security precautions, a small group of visitors, including Hammond's grandchildren, struggle to survive and escape the now perilous island.
