Two astronauts and a sympathetic chimp friend are fugitives in a future Earth dominated by a civilization of humanoid apes.

Based on the 1968 Planet of the Apes film and its sequels, which were inspired by the novel of the same name by Pierre Boulle.

Astronaut Brent is sent to rescue Taylor but crash lands on the Planet of the Apes, just like Taylor did in the original film. Taylor has disappeared into the Forbidden Zone so Brent and Nova try to follow and find him. He discovers a cult of humans that fear the Apes’ latest military movements and finds himself in the middle. Tension mounts to a climactic battle between ape and man deep in the bowels of the planet.
