Told as a flashback to the early 21st century, with a wraparound sequence narrated by the orangutan Lawgiver in "North America – 2670 A.D.", this sequel follows the ape leader Caesar years after a global nuclear war has destroyed civilization. Living with his wife, Lisa and their son, Cornelius, Caesar creates a new society while trying to cultivate peace between the apes and remaining humans. Caesar is opposed by a gorilla named Aldo, who wants to imprison the humans who freely roam Ape City while doing menial labor.
