After being constantly attacked by the humans, despite asking for peace, Caesar and the Apes decide to find a new home safe from the humans. But after the tragic deaths of the most recent attack from the humans, Caeser embarks on a mission to kill the ruthless human Colonel.—Ronald Pickleson

Two years after the misanthropic bonobo Koba attacked the human survivors in San Francisco, Caesar and his tribe of intelligent apes have been forced against a rogue U.S. military faction known as Alpha-Omega led by a ruthless colonel. Alpha-Omega employs other apes formerly loyal to Koba, derogatorily called "donkeys". An Alpha-Omega platoon launches an attack on an ape outpost, but it fails and four soldiers, including one named Preacher and a "donkey" gorilla named Red, are captured. Caesar releases the soldiers, hoping the display of mercy will show the Colonel that the apes are not savages; Red escapes by injuring the albino gorilla Winter. Later, Caesar's eldest son Blue Eyes and lieutenant Rocket return from a long journey. Blue Eyes reports that they found a place across the desert that is ideal for the apes. Despite an uneasy Winter asserting that the apes should leave immediately, Caesar decides they need to prepare first. That night, the Colonel leads a team of soldiers in infiltrating the apes' home, killing Blue Eyes and Caesar's wife Cornelia; Caesar unsuccessfully attempts to prevent the Colonel's escape. Afterward, the apes are unable to find Winter, who they believe betrayed them out of fear.

A few years after Koba's uprising, Caesar and his ape tribe are put to the ultimate test when they find that the conflict with humans is escalated by a powerful new enemy who seeks to destroy Caesar and his family. While Caesar, Maurice, Rocket and their tribe have suffered so much loss and pain, Caesar finds that he must fight the evil within himself as he must make one final stand to save his people in a war that will determine both the future of his people and the world.—Blazer346

In 2028, two years following the Battle of San Francisco, a U.S. Army battalion known as "Alpha-Omega" aided by apes derogatorily called "donkeys", searches for Caesar's ape colony. A platoon assault an ape outpost, but the apes repel the attack and kill all but four humans and a donkey gorilla named Red. Caesar releases the captured humans as a peacekeeping gesture, but Red escapes after attacking Winter. Caesar's young son Blue Eyes and Rocket return from a scouting expedition to report they have found an oasis that could serve as a safer home. That night, the Colonel of Alpha-Omega leads a team to infiltrate the colony and kills Cornelia and Blue Eyes, mistaking the latter for Caesar. Cornelius, Caesar's younger son, manages to survive the attack by hiding while the Colonel escapes.

Caesar, followed by Rocket, Maurice, and Luca, decide to serve as decoys while the tribe journeys to the oasis. In an abandoned village, Caesar kills a human in self-defense and finds his mute daughter, whom Maurice - with Caesar's begrudging consent - takes guardianship of, giving her a rag doll. They encounter Winter, now working for Alpha-Omega after giving away their hideout, having faked the attack by Red and letting him escape, and confront him. He reveals that the Colonel is heading north to meet up with the rest of the military forces. Caesar accidentally kills Winter in retribution for his wife and son, and to prevent him from alerting the soldiers. As they follow the Colonel, Caesar's group discovers several dead soldiers who have been executed by their own troops; a fatally wounded survivor is revealed to be mute, just like the girl. Caesar's group chases someone who has stolen one of their horses and discovers the thief is another intelligent ape, Bad Ape, who matured in isolation. He guides them to a former weapons depot-turned quarantine facility in the mountains that serves as the base for the militia. A human patrol kills Luca, and an enraged Caesar tells Maurice, Rocket, Bad Ape, and the mute girl to turn back. Caesar attempts to infiltrate the base and discovers his tribe has been captured and forced into labor there before he is caught by Red. Caesar deduces that the militia are using the apes to barricade the facility in order to fend off the incoming military forces, which intend to attack rather than reinforce the militia.

The Colonel reveals that the Simian Flu virus has mutated, causing infected humans to mentally devolve into primitive animals, depriving them of their intelligence. After killing his infected son, he ordered his own troops to kill any carriers before they could infect others. This led to a conflict with his superiors, who believed the disease could still be cured, and are coming to forcibly relieve the Colonel of his command. The Colonel has Caesar tortured, starved and leaves him exposed to the cold. The mute girl, named Nova by Maurice, sneaks into the facility to feed Caesar. Rocket allows himself to be captured to prevent Nova from being seen so he and Caesar can formulate a plan to escape. The Colonel later confiscates the doll Nova left for Caesar, but the other apes escape via an underground tunnel.

The military arrives and attacks the facility, and the apes are caught in the crossfire. During the chaos, Caesar sneaks into the Colonel's quarters to kill him, only to find that the virus has infected him after handling Nova's doll. Caesar refuses to kill the Colonel, instead allowing him to kill himself. Caesar then attempts to destroy a fuel tank but is critically wounded by Preacher, one of the soldiers he released earlier. At the sight of the apes being killed, Red has a change of heart and kills Preacher before being executed. Caesar blows the fuel tank, causing an avalanche that buries both armies and flees up the trees with the rest of the apes and Nova.

The apes and Nova resume their journey to the oasis. As they arrive, Maurice discovers Caesar's wound and promises that Cornelius will know who his father was and what he did for the apes. With his colony safe in their new home, Caesar peacefully passes away.
