A cyborg, identical to the one who failed to kill Sarah Connor, must now protect her ten-year-old son John from a more advanced and powerful cyborg.
Over 10 years have passed since the first machine called The Terminator tried to kill Sarah Connor and her unborn son, John. The man who will become the future leader of the human resistance against the Machines is now a healthy young boy. However, another Terminator, called the T-1000, is sent back through time by the supercomputer Skynet. This new Terminator is more advanced and more powerful than its predecessor and its mission is to kill John Connor when hes still a child. However, Sarah and John do not have to face the threat of the T-1000 alone. Another Terminator (identical to the same model that tried and failed to kill Sarah Connor in 1984) is also sent back through time to protect them. Now, the battle for tomorrow has begun.
In 1995, one long decade after the Terminators failed assassination mission in , a now-ten-year-old John Connor finds himself in foster care, after the imprisonment of his mother, Sarah, at a mental institution. To prevent John from changing the course of history and becoming the leader of the human Resistance Army, the self-aware computer system, Skynet, sends another cybernetic assassin; this time, a nearly indestructible, shape-shifting killer. Now, against the backdrop of an imminent nuclear Armageddon, two unstoppable cyborgs--the antiquated but lethal, T-800, and the far superior, liquid-metal model, T-1000--are after the same vulnerable target. Can Sarah and John avert the coming Judgment Day?
