After the huge nuclear conflagration of August 29, 1997, the few surviving humans, led by John Connor, fight relentlessly against the robot army led by Skynet, a super-powerful computer. Skynet first tries to eliminate Sarah Connor, John's mother, with a cyborg projected in 1984, but in vain. He then transfers a second robot, T1000, into the past and sends it to the time when John Connor was still a child.
