Conquest of the Planet of the Apes

Circus director Elmundo (Ricardo Montalban) takes in and protects a helpless orangutan, named Caesar (Roddy McDowall). Under Elmundo's meticulous care, Caesar gradually grew up, and the relationship between him and his "father" Elmundo was very close. A raging virus has caused cats and dogs to become extinct on the earth, and they have lost their most loyal friends. Humans who need the companionship of animals have turned their attention to orangutans who are very similar to them. In this way, raising orangutans as pets has become a new fashion. However, the cruel nature of humans has made the lives of these originally docile and kind-hearted orangutans miserable. They were tortured and abused, and they lost their freedom forever. Finally, the orangutans decided not to tolerate it any longer. Under the leadership of Caesar, they bravely revolted and vowed to overthrow human oppression and rule.
