Nada (Roddy Piper), a wanderer without meaning in his life, discovers a pair of sunglasses capable of showing the world the way it truly is. As he walks the streets of Los Angeles, Nada notices that both the media and the government are comprised of subliminal messages meant to keep the population subdued, and that most of the social elite are skull-faced aliens bent on world domination. With this shocking discovery, Nada fights to free humanity from the mind-controlling aliens.

John Hammond (Richard Attenborough) summons chaos theorist Ian Malcolm (Jeff Goldblum) to his home with some startling information -- while nearly everything at his Jurassic Park had been destroyed, his engineers happened to have a second site, where other dinosaurs were kept in hiding. It seems the dinosaurs on the second island are alive and well and even breeding; and Hammond wants Malcolm to observe and document the reptiles before Hammond's financiers can get to them.
