Lena Headey and Summer Glau co-star in which American TV series?

"Terminator: The Sarah Connor Chronicles" (sometimes abbreviated as "Terminator: TSCC" or simply "TSCC") was an American science fiction television series that aired on Fox from January 2008 to April 2009. It is a spin-off from the "Terminator series" of films. It revolves around the lives of the fictional characters Sarah and John Connor, following the events of "Terminator 2: Judgment Day".

Sarah Connor (Lena Headey) is a major character in the Terminator series. She is the mother of John Connor, who will one day become the leader of the human resistance. The authorities, however, see her as a deranged fugitive.

Cameron (Summer Glau) is a Terminator whom John Connor sent back from 2027 to protect his earlier self. Her model and exact capabilities are not known, but she can mimic human mannerisms better than the T-800 model could, and she can also consume small amounts of food, a first for Terminators.
