Kingdom of the Planet of the Apes (2024): Cast, Plot and Ending Explained

The full plot of Kingdom of the Planet of the Apes follows Noa from the burning of his village to the flooding of a sealed human vault and the unanswered question that closes the film.

After the raid, Noa travels in search of his clan and is joined by Raka, who teaches him Caesar's original ideas. They come across a human scavenger who turns out to be able to speak, and she is called Mae. Raka is swept away while saving her, and Noa and Mae are then captured and taken to the coastal kingdom of Proximus Caesar. Proximus has enslaved many clans, including Noa's, to force open a sealed human vault that he believes holds powerful technology.

Proximus keeps a human advisor named Trevathan, who tells Noa about the human past. Mae reveals that she wants something from the vault, and Noa agrees to help her while he tries to free his people. Trevathan catches them planting charges, and Mae kills him. Inside the vault Mae sets off the explosives, which flood the area and let the captives escape.

Noa traps Sylva in the flooding bunker, then leads his clan and their eagles against Proximus, who falls from a cliff into the sea. The clan goes home to rebuild. Mae says goodbye while secretly armed, then travels to a human satellite base, where she uses the data she took from the vault to switch the satellites back on and contact other human settlements. Noa and Soona look through a telescope, and what they see is left open.

The ending of Kingdom of the Planet of the Apes closes Noa's story and opens a larger one: the apes are free, but Mae now holds the means to reconnect the surviving humans.

What happens to Proximus and the clans? Proximus falls from a cliff into the sea after Noa leads his clan and their eagles against him, and the enslaved clans are free. Noa traps Sylva, who led the raiders, in the flooding bunker, and then leads his people home to rebuild.

What does Mae do with the vault? Mae takes the key technology out of the vault and travels to a human satellite base. She uses the data to switch the satellites back on and contact other human settlements. That aim explains why she was willing to kill Trevathan and flood the vault to get what she wanted.

Why does her goodbye matter? She says farewell to Noa while secretly armed. In my opinion, that detail is the film's clearest hint that peace between the species is temporary, because a human with working satellites and a weapon is a different prospect from the mute, scavenging humans Noa grew up around.

What does Noa see through the telescope? The film does not say. Noa and Soona look through a telescope and the camera leaves the answer open. It could be argued that this is deliberate, because it keeps the next conflict between apes and humans undefined rather than naming it.

Is this a setup for a sequel? The ending leaves room for one, but the next announced Apes film does not follow it up directly. TheWrap reported in May 2026 that Matt Shakman is directing an untitled Apes film for 20th Century Studios from a screenplay by Josh Friedman, and that it is a new original story rather than a sequel to Kingdom. No release date is confirmed, as covered on the Kingdom of the Planet of the Apes sequel page.

What about Caesar? The film is set many generations after his death. His teachings are passed on by Raka, and his name is borrowed by Proximus. In my opinion, that is the film's central tension: the same legacy can be used to free apes or to rule them.
