On a planet where apes talk and walk like men, and men are primitive
animals, an astronaut from Earth, Taylor, crash lands and is captured by
gorilla soldiers. Thinking he is just another primitive human, the apes
imprison Taylor with the beautiful but silent Nova. With help from their
chimpanzee captors, Cornelius and Zira, Taylor and Nova make a daring
escape into the Forbidden Zone, where they stumble upon the horrible
secret of The Planet of the Apes.
