Earthling Davidge (Dennis Quaid) is one of many space warriors facing a brutal battle against the reptilian Draconians, among them the soldier Jeriba (Louis Gossett Jr.). But when the pilots’ spaceships crash-land on the same planet, these foes must team up to stay alive. The stakes climb higher after Jeriba gives birth to a baby Drac, and Davidge becomes foster father to his own natural enemy as he tries to survive in a hostile land.
