A substance, designed to help the brain repair itself, gives rise to a super-intelligent chimp who leads an ape uprising.
Will Rodman, a scientist at 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, but 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 disease, names the chimp “Caesar”. 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.
As Caesar gets older he gets more curious about the world and its wonders. Just like a regular kid, Caesar is curious. Troubles within the neighbors occur and conflicts arise within the neighborhood. Caesar as a kid ended up straying off and getting into the neighbors yard. This neighbors name is Hunsiker who attacked caesar as he was curious as a little chimp. This time Wills father Charles goes into his car and tries to drive it. Hunsiker ends up assaulting Charles and pulls him out the car. Caesar watches and ends up getting out the house to protect Charles from Hunsiker.
While protecting Charles, Caesar, ends up beating and biting off the finger of Hunsiker. This makes a change of events which makes Caesar have to be put under control and sent to a ape shelter you can say. In this shelter it holds a gorilla, a orangoutang and dozens of apes.
Caesar is then placed in a primate shelter where he is treated cruelly by the other chimps and the chief guard, Dodge Landon.Caesar learns how to unlock his cage, gaining free access to the common area. With the assistance of Buck, a gorilla, he confronts the sanctuary’s alpha chimp and claims that position.
