In 2029, John Connor, leader of the Resistance, continues the war against the machines. At the Los Angeles’ offensive, John’s fears of the unknown future begin to emerge when John is notified by his army unit, Tech-Com, that Skynet will attack him from two fronts, past and future, and will ultimately change warfare forever.

On the verge of winning the war against Skynet, Connor sends his trusted lieutenant Kyle Reese back through time to save his mother’s life and ensure his own existence. However, Kyle finds the original past changed. After being orphaned at age nine by a T-800, sent to kill her when she was young to prevent the future, Sarah Connor has been brought up by another Terminator T-800 programmed to protect her. This Terminator has then trained her to face her destiny, which she adamantly tries to reject. Now, Kyle and Sarah have to escape the new T-800 and the T-1000 sent by Skynet to kill them, with the help of the old Terminator.
