<P> When the group arrives at the border, they see hundreds of apes held captive inside a former quarantine facility . While getting a closer look, Luca is killed protecting Caesar from an Alpha - Omega patrol, angering Caesar and causing him to proceed alone . Caesar discovers the rest of his ape clan has been captured, and are being forced to build a wall with no food or water; he is captured by Red . The Colonel reveals to Caesar that the Simian Flu virus has mutated and now causes humans who survived the original strain to become mute, which he believes is a sign of devolution to a primitive state . Caesar deduces that the Colonel is barricading himself in the facility to fend off remnants of the U.S. Army from the north who are coming to execute him because he favors massacring any infected humans, including his own son, to stop the spread of the virus . Caesar is commended by the Colonel for his intelligence, and the Colonel explains that he is fighting a "holy war" for humanity's survival . </P> <P> While Caesar is tortured with starvation, the mute girl, whom Maurice names Nova, sneaks into the facility to give Caesar food, water, and her rag doll (originally given to her by Maurice). To prevent Nova from being discovered, Rocket allows himself to be captured as a diversion . The next day, the Colonel comes to see if Caesar is still alive, and confiscates Nova's doll upon discovering it . Together Caesar and Rocket are able to work out a means of escape via an underground tunnel that leads out of the facility . Maurice and Bad Ape use the tunnel to rescue the apes, and Caesar orders the others to escape while he goes to confront the Colonel as the facility comes under attack by the northern army . Caesar reaches the Colonel and prepares to kill him, but discovers that Nova's doll has infected him with the mutated virus, rendering him unable to speak . Caesar spares the Colonel and watches as he uses his pistol to commit suicide, rather than regressing to a primitive state . </P> <P> During the battle between Alpha - Omega and the northern army, the escaping apes come under fire from Alpha - Omega . Caesar attempts to attack Alpha - Omega forces from behind, but is shot with a crossbow by Preacher, one of the Alpha - Omega soldiers he had previously set free . In an act of redemption, Red saves Caesar's life by killing Preacher with a grenade launcher, and gets shot by an Alpha - Omega superior as a result . Caesar blows up a large fuel tank, causing a cascade of explosions which destroys the Alpha - Omega facility, allowing the northern army to win the battle . However, the army is subsequently devastated by an avalanche, which Caesar and the other apes, carrying Nova, survive by climbing nearby trees . </P> <P> The remaining apes depart the facility and cross the desert to find an oasis . While the other apes joyously celebrate their new home, Maurice discovers Caesar's wound . Maurice then speaks, telling the dying Caesar that Cornelius will know who his father was, what he stood for and what he did to protect the apes . Caesar then slowly and silently succumbs to his wounds, dying peacefully while Maurice mourns his passing as the other apes look on . </P>
