XIII (2008) - 1x01 - Episode 1

The first female President of the United States is assassinated during her Veterans Day speech. Three months later, with the case still unsolved, a young man (Stephen Dorff) is found unconscious in the woods. Suffering from amnesia he discovers a tattoo on his chest of the Roman numeral XIII, a photograph and a computer chip, which seem to be his only clues to his past. He soon realizes he's an army man, trained for covert operations and finds himself on the run -- not only from government agents and the police, but also from the determined mercenary The Mongoose (Val Kilmer), and his men. The young man known as, XIII, learns he is being accused of assassinating the President and attempts to stay alive, uncover the real conspirators, and discover his true identity.
