Based on the phenomenally popular Terminator movie franchise, the Fox network's Terminator: The Sarah Connor Chronicles was not a sequel to the third theatrical film in the series, Terminator 3: Rise of the Machines -- nor could it have been, since that particular epic ended with the destruction of civilization and the death of the heroine. Instead, the Fox TV series picked up the action where the second of the three films, Terminator 2: Judgment Day, left off, going its merry way as if Terminator 3 never existed. After the reprogrammed T-800 Model 101 Terminator (the role played in the second film by Arnold Schwarzenegger) had sacrificed itself to save humanity, Sarah Connor (Lena Headey) and her 15-year-old son John (Thomas Dekker) -- who was destined to grow up and lead a resistance movement against the rulers of post-apocalyptic Earth -- were stalked by the futuristic agents of the covert US government project Skynet. Just as the titular robotic villain of the original 1984 Terminator movie had sent been back into time to kill Sarah Connor so that John would never be born, so too had the bad guys travelled backward to 2007 to knock off both John and Sarah. Fighting fire with fire, the Connors became fugitives from the law, dedicating themselves to preventing Skynet from being created -- and, ultimately, from devastating the earth in a nuclear holocaust. They were aided by Connor's mysterious classmate Cameron Phillips (Summer Glau), who was actually a "good" reprogrammed Terminator dispatched from the Future to protect Sarah and the teenage John Connor by the "grown-up" version of John. Unfortunately, evil Terminators continued popping up everywhere, notably a "substitute teacher" named Mr. Cromarite (Owain Yeoman in the pilot episode, Garret Dillahunt thereafter), who in the pilot episode set the series' plot in motion. Also in pursuit of the fugitive Connors was human FBI agent James Ellison Richard T. Jones. Terminator: The Sarah Connor Chronicles debuted January 13, 2008.
