Conquest of the Planet of the Apes

In 1983 (several years after the end of Escape from the Planet of the Apes), a disease kills the world's cats and dogs, leaving humans with no pet animals. To replace them, humans began keeping monkeys and apes as household pets. In time, humans notice the apes' capacity to learn and adapt; thus they train them to perform menial household tasks. By 1991, the United States of America has become an oppressive and fascist culture of uniformed classes and castes, based upon ape slave labor.
