A human soldier is sent from 2029 to 1984 to stop an almost indestructible cyborg killing machine, sent from the same year, which has been programmed to execute a young woman whose unborn son is the key to humanity's future salvation.

Sent back from a dystopian 2029--where the cold machines have conquered the entire world--to 1984 Los Angeles, the indestructible cyborg-assassin known as the "Terminator" commences his deadly mission to kill humankind's most important woman: the unsuspecting, Sarah Connor. However, from the same war-torn post-apocalyptic future comes a battle-scarred defender--Kyle Reese, a brave soldier of the human Resistance Army--bent on stopping the cybernetic killer from eliminating the world's last hope. But, the Terminator has no feelings, he doesn't sleep, and above all, he won't stop until he carries out his grim task. Does our future lie in our past?
