A decade has passed since John Connor (NICK STAHL) helped prevent Judgment Day and save mankind from mass destruction. Now 25, Connor lives "off the grid" - no home, no credit cards, no cell phone and no job. No record of his existence. No way he can be traced by Skynet - the highly developed network of machines that once tried to kill him and wage war on humanity. Until, out of the shadows of the future steps the T-X (KRISTANNA LOKEN), Skynet's most sophisticated cyborg killing machine yet.
