Planet of the Apes

Astronauts Alan Virdon and Peter Burke crash land on a strange planet. After being rescued by a friendly human, Virdon and Burke discover this planet is ruled by intelligent apes. To their horror, they discover that they are back on Earth in the year 3085.

In a ruined city, Burke and Urko are trapped underground and must reluctantly work together to escape, while Alan and Galen must deal with Urkos gorilla patrol in the streets above.

Burke and Virdon are helped by a young woman and a young boy while searching for an underground computer in a ruined city, but their plans go awry when Alan is captured and Urko uses the boy to get information from the astronaut.

Galen must use all his charm to try and persuade his ex-girlfriend, a female ape surgeon named Kira, to operate on Virdon using a forbidden human anatomy book, after the astronaut is shot.

Virdon decides to take part in a dangerous horse race even though he runs the risk of being captured by Urko.

Aboro, a despot, is making community life a misery; Burke, Virdon, and Galen decide to rob him of his powers.

Burke and Virdon are captured by a bunch of humans determined to hand them over to the Apes.
