Life on Mars Temporada 1 Episódio 7

Sam demands a transparent investigation into the death-in-custody of small-time drug dealer Billy Kemble. He believes that if the police dont police themselves, the public will never trust them. When the explosive evidence of what happened to Billy falls into his hands, Sam has a huge decision to make. This evidence could tear the team apart. Its an opportunity to destroy his world and the people in it, but also perhaps an opportunity to get home.
