Conquest of the Planet of the Apes 1972

1991 North America is a police state in which cats and dogs have been wiped out by a virus brought back from space by astronauts. Apes are imported from Africa and auctioned off as household pets and trained to perform menial tasks. A circus owner named Armando arrives in the city with a grown ape named Caesar. Eighteen years earlier, Armando had hidden the baby Caesar, whose parents were intelligent and articulate apes who had traveled back from the 22nd century and were killed in an attempt to prevent future ape domination.
