Battle For the Planet of the Apes (1973) is the fifth and final entry in the Planet of the Apes series.

Set in flashback to the turn of the 21st century, this sequel focuses on the ape leader, Caesar, about a decade or so after he led the ape revolution in the previous film, Conquest of the Planet of the Apes. In this post-nuclear war society, Caesar tries to cultivate peace between his simian peers and the surviving remains of humanity. Gorilla leader, Aldo, however, wants nothing to do with this, as it reminds him of his former enslavement, so he plots Caesar's overthrow and doom, as do a band of mutated humans from their former city of the last film who want to reclaim Earth and destroy the entire ape society.
