Reign of the Planet of the Apes is a 2019 sequel to the 2011 film Rise of the Planet of the Apes, 2014 film Dawn of the Planet of the Apes, and 2017 film War of the Planet of the Apes with Matt Reeves planning to return as director.

Synopsis
13 years after the events of War of the Planet of the Apes, Cornelius is the leader of the apes during a nuclear war between the remaining armies including the Alpha-Omega. After a nuke is dropped near the apes, a gas is released which is the mutated version of simian flu that makes people mute but has a different effect on the apes. The apes then must journey to safety.

Plot
Thirteen years after Caesar led the apes in a rebellion against Colonel McCullough and the Alpha-Omega army, his son Cornelius is leading the country with Maurice as his advisor. The ape clan has found themselves in the middle of a nuclear war between different groups of humans with the mutated simian flu continuing to ravage the human population that is still left. New bombs are being created that release gas when they come into contact with the ground. One hits in the oasis and releases gas and all the ape's breathe in the gas but nothing happens. Cornelius, Bad Ape, Maurice, Nova, Rocket, Maruikei (an albino gorilla), and Akamaru (a gorilla) hold a council to decide if it is time to move further inland. They unanimously agree. The next day they move out. Later in the night, they stumble upon a small group of humans that run from the apes but they aren't fast enough and the apes catch up. These humans can't talk. The apes let them go. The next day they encounter a small group of apes that can talk and also stand on their hind legs. There is a standoff between the two colonies. Gunfire erupts and four apes from the new colony are killed but the leader of this new colony comes out. His name is Aono Zaius. These apes look considerably different than others. They are more human-like and they can talk.

The apes stay there for a while and the two governments decide to join forces and become one. Strange things start to happen to some more apes. They develop speech. As they journey they see ahead in the distance nukes raining down on a vast mountain range.
