Watch Beneath the Planet of the Apes
"Beneath the Planet of the Apes" is the second in a series of five "Planet of the Apes" movies which gives a science fiction account of what could happen if apes and humans traded places. The apes become humans and the humans are perceived by them to be animals in this mind-bending adventure tale of destruction, hate and unusual forms of racism and animal cruelty. Brent, the lone surviving astronaut of a rescue mission, arrives at the planet to save Taylor, who had been stranded there in the first movie of the series. As the story progresses, we find that there is a population of humans beneath the surface of this planet who are unwittingly worshiping a nuclear bomb from earth's past, not knowing that it is a very sensitive and destructive tool.
