Life on Mars

Gene believes that local gangster Stephen Warren and the police can co-exist and that the streets are safer as a result. But Sam knows that in the future, dodgy deals like this will irrevocably change the relationship between the public and the police. Whilst Gene lays a ghost to rest, Sam sets to work on convincing his new partner, but is distracted when he meets his mother as a young woman.

Sam and Gene go undercover in a local pub to solve the murder of a local Manchester United fan. As Gene looks like he's set to drink the pub dry, Sam worries about their chances of finding the killer before Saturday's big match. With the press using the murder to fuel the flames of hate between rival fans, Sam is under pressure to solve the murder before the tensions destroy the community.

When his mother's voice bleeds through from 2006 and he hears her say goodbye to him, Sam is desperate - he's alive and determined to make himself heard. But then the call comes in that a man has taken people hostage at the Manchester Gazette and is intent on killing them at 2pm - the same time Sam's machine will be switched off. Could stopping the hostage-taker be a way of staying alive?

Sam demands a transparent investigation into the death-in-custody of small-time drug dealer Billy Kemble. He believes that if the police don't 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. It's an opportunity to destroy his world and the people in it, but also perhaps an opportunity to get home.
