In 2805, Earth is long-abandoned and covered in heaps of garbage leftover from decades of mass consumerism, facilitated by the megacorporation Buy 'n' Large (BnL).

In 1995, John Connor is ten years old and living in Los Angeles with foster parents. His mother Sarah Connor had been preparing him throughout his childhood for his future role as the leader of the Human Resistance against Skynet, but was arrested after attempting to bomb a computer factory and imprisoned at a mental hospital under the supervision of Dr. Silberman. Skynet sends a new Terminator, designated as T-1000, back in time to kill John. The T-1000 is an advanced prototype composed of a mimetic polyalloy that allows it to take on the shape and appearance of almost anything it touches, and transform parts of its anatomy into knives and other stabbing weapons. The T-1000 arrives under a freeway, kills a policeman and assumes his identity. Meanwhile, the future John Connor has sent back a reprogrammed T-800 (Model 101) Terminator to protect his younger self.
Deux ans après avoir affronté les humains et Koba, César et les singes vivent reculés dans une forêt. Leur avant-poste est alors attaqué par une unité militaire pratiquement annihilée dans l'assaut et qui subit une défaite totale, rapportée par radio à leur commandant le colonel McCullough. Selon les dires d'un survivant fait prisonnier et présenté à César, cet homme sanguinaire cherche à tout prix à retrouver César pour installer la domination des hommes sur les primates : bien que ça ne fasse pas l'unanimité, César choisit d'épargner les soldats survivants et de les lui renvoyer avec un message de laisser tomber afin de clarifier les circonstances ayant amené cette situation et prévenir une montée vaine des conflits. Plus tard alors qu'ils s'occupent de leurs morts et blessés, César vient accueillir son fils aîné Yeux-Bleus et Rocket, qui reviennent d'une expédition prolongée et ont apparemment enfin trouvé la terre promise des singes, à des mois de marche de là. Le soir même, après des discussions houleuses sur la suite des événements et la crainte exprimée par Winter, un gorille albinos, la décision est prise de s'y rendre. Mais après l'échec de ses soldats, le colonel McCullough se déplace en personne avec un commando dans le refuge de César afin de le tuer. Il tue le fils aîné de César par méprise ainsi que sa compagne, Cornelia, épargnant sans le savoir leur enfant cadet, Cornelius qui s'était caché. César qui arrive juste avant son départ et constate leur mort, tente de se venger pour son acte mais échoue de peu. Tandis que la colonie a débuté son trajet vers leur futur foyer, César confie alors Cornelius à Lake, la compagne de feu son fils aîné, puis quitte les siens à leur grande surprise pour se lancer seul à la poursuite de McCullough, assoiffé de vengeance. Il est toutefois vite rattrapé et épaulé par ses plus proches amis l’orang-outan Maurice, le chimpanzé Rocket (dont le fils Ash, meilleur ami de Yeux-Bleus, fut également tué, par Koba en son temps) et le gorille Luca.
Will Rodman, a scientist at the biotechnology company Gen-Sys, is testing viral-based drug ALZ-112 on chimpanzees to find a cure for brain ailments such as Alzheimer's disease. The drug is given to a chimpanzee, Bright Eyes, greatly increasing her intelligence. However, when Will is presenting 112 to his boss and uses Bright Eyes as an example, she is forced from her cage, goes on a rampage, and is killed. Will's boss Steven Jacobs terminates the project and orders chimp handler Robert Franklin to euthanize the chimps. After doing as ordered, Franklin discovers that Bright Eyes had recently given birth and understands the reason why she was disturbed. He convinces Will to save the baby chimp's life by taking him home temporarily. Will's father Charles, who is suffering from Alzheimer's, names the chimp "Caesar", in reference to William Shakespeare's play Julius Caesar, from which he can, despite his deteriorating mental condition, cite long passages from memory. Will learns that Caesar has inherited his mother's high intelligence (the 112 virus passing to him in utero) and decides to raise him, working from home and observing his behavior in hopes that he can get the project restarted. Three years later, Will introduces Caesar to the redwood forest at Muir Woods National Monument. Meanwhile, with Charles' condition rapidly deteriorating, Will treats him with ALZ-112 and he is restored to better-than-original cognitive ability.

John Connor has been living off the grid in Los Angeles in the years following the death of his mother, Sarah, from leukemia. Although Judgment Day did not occur on August 29, 1997, as expected, John still believes that a war between humans and the machines will occur. Unable to locate John in the past, Skynet sends a new model of the Terminator called the T-X back to July 24, 2004 to kill other members of the Human Resistance. The T-X is more advanced than previous Terminators, and has an endoskeleton with built-in weaponry, a liquid metal exterior similar to the T-1000, and the ability to reprogram other machines. Unlike previous Terminators, its standard appearance is female. The Resistance sends a reprogrammed Terminator (T-850 - Model 101) back in time to protect the T-X's targets including John and his future wife, Kate Brewster.
