Solar Warriors (aka Solarbabies)

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.
