Told as a flashback to the early 21st century with a wraparound sequence narrated by the orangutan Lawgiver (John Huston) in "North America - 2670 A.D.", this sequel follows the ape leader Caesar (Roddy McDowall) years after a global nuclear war has destroyed civilization. In this post-nuclear society, Caesar tries to cultivate peace between the apes and the surviving humans. A gorilla general named Aldo (Claude Akins) however opposes this and plots Caesar's downfall. Caesar is married to Lisa (Natalie Trundy), the female ape of the previous film, and they have a son named Cornelius (Bobby Porter) in honor of Caesar's father. (thetvdb.com)
