"Terminator: The Sarah Connor Chronicles" reveals what happens when Sarah Connor (series star LENA HEADEY) goes on the offensive against an ever-evolving technological enemy bent on destroying her life -- and perhaps the world. At the end of "Terminator 2: Judgment Day," Sarah vanquished the Terminator sent from the future to kill her 15-year-old son. Now Sarah and her son, John (series star THOMAS DEKKER), find themselves alone in a very dangerous, complicated world. Fugitives from the law, they are confronted with the reality that still more enemies from the future and the present could attack at any moment. As Sarah confronts reality, John knows that he may be the future savior of mankind, but he is not yet ready to take on the mantle of leadership that he's told is his destiny. He finds himself inextricably drawn to Cameron (series star SUMMER GLAU), an enigmatic and otherworldly student at his high school. Cameron soon proves to be much more than his confidante, as she assumes the role of fearless protector of both Sarah and John. On their trail are threats from the future, but also an intelligent and tough FBI agent, James Ellison (series star RICHARD T. JONES), who soon becomes a powerful ally. "Terminator: The Sarah Connor Chronicles" represents an exciting reinvention of the "Terminator" franchise, in which the strong and intrepid Sarah discovers that protecting her son and stopping the rise of the machines is more difficult than she had ever imagined. In the series premiere, again facing relentless Terminators that will stop at nothing until John, the future leader of the resistance, is eliminated, Sarah Connor stops running and starts fighting back against fate and the machines that are out for her son.
