When Sam responds to a fatal stabbing at Crester's Textiles he's shocked to discover that it's the converted mill where he lives in 2006. Sam sets up a forensic investigation but Gene already has a hunch about the murderer. Sam believes he has to stop Gene from sending an innocent man down for life. But does he have more to learn about this world than he thinks?

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.

On an assignment to return a career safe breaker from prison for further questioning, Tyler, Ray and Chris are attacked by robbers and the man who they were taken in for questioning is broken out. Is a local gangster to blame, or is there more going on than meets the eye... specifically, was the crime actually arranged by Gene's old mentor? Meanwhile, Sam tries to break in the first black detective in the department, a man who will later become Sam's mentor when he first joins the police force.
