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.
