Beneath the Planet of the Apes

Following the events of Planet of the Apes, time-displaced astronaut Taylor and the mute Nova are riding on horseback through the desert of the Forbidden Zone.  Elsewhere in the Forbidden Zone, a second human spaceship has crash-landed after being sent in search of Taylor and his crew. Like Taylor's ship, it has traveled forward through time into Earth's distant future. However, surviving astronaut Brent is unaware of this and believes he has traveled to another planet.
