In 2018, humanity enters a war with machines. John Connor is a man who is destined to lead the resistance against Skynet and the army of Terminators. From the recordings his mother has left him, he knows he has to find Kyle Reese and send him back to Earth if the future is to occur as it should. Reese is just a teenager now, on the run like many other humans. While in the company of another survivor, Marcus Wright, Kyle is taken prisoner by the machines and transported to Skynet's headquarters in San Francisco. Connor sets out to rescue him but is shocked by Wright's true nature. Not all is at it seems to be and success is far from guaranteed.
