Terminator: The Sarah Connor Chronicles represents an exciting reinvention of the Terminator franchise, in which the strong and intrepid Sarah Connor (Lena Headey) discovers that protecting her 15-year-old son, John (Thomas Dekker), and stopping the rise of the machines is more difficult than she had ever imagined. Sarah and John are joined by Cameron (Summer Glau), an enigmatic and otherworldly high school student, who proves to be much more than a friend and James Ellison (Richard T. Jones) an FBI agent hot on their trail who soon becomes a powerful ally.
