In the late Cretaceous period of Earth's history, iguanodon Aladar (voiced by D.B. Sweeney) is separated from his own species while still inside his egg. He is taken in and brought up by lemurs Zini and Plio, but when this adoptive family is all by wiped out by a meteor shower, Aladar and his friends are forced to join a mixed herd of dinosaurs who are migrating to a new nesting ground. This tribe is led by the hard-headed Kron (Samuel E. Wright), whose 'survival of the fittest' approach clashes with Aladar's more altruistic nature.

Richard Jordan, Jami Gertz and Jason Petric star in this futuristic sci-fi drama. Set in a post-apocalyptic future where most of Earth's water has disappeared and the planet is ruled by the Eco Protectorate corporation, the story follows a group of teen skateboarders who are held captive in an orphanage on the desert planet. After the group's leader Grock (Jordan) discovers a magical orb, the teenagers rebel against their megalomaniac ruler and, with the help of a group of outlaws known as the Eco Warriors, try to restore water to the Earth.
