Catapulted 2000 years into time and space, a team of American astronauts crash lands on an unknown planet dominated by a strange but intelligent simian population. The humans are soon captured by a band of gorilla soldiers, and those who survive are held captive in laboratory cages. Here, apes consider humans to be animals...hunted for sport and butchered for medical experimentation. Their existence threatens simian survival, for reasons known only to the ape hierarchy! Who will finally emerge as the master race - man or ape?
