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 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.

Sam is finally accepting of this world - until he comes face to face with his 29 year-old dad, Vic. Vic Tyler is a small time gambler who unwittingly finds himself at the centre of a murder enquiry. As Sam moves to protect his father, he embarks upon an emotional journey, piecing together a childhood memory and uncovering an uncomfortable truth that will change him forever.

Tyler has visions of someone disrupting his life support system in 2006, and encounters who he thinks is the same assailant in 1973, running a gambling syndicate and protection racket. Recognising the man as a killer he failed to stop in the future, Tyler is prepared to go to any lengths to make sure his life is not threatened and the man doesn't kill his original victim.

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.

The team receive a bomb warning, claiming the IRA has planted a car bomb in Manchester. Being from 2006, Sam realises the bomb warning reported doesn't fit with his understanding of IRA methods. However, when Sam's modern know-how fails and nearly kills Ray, the rest of the department shun his line of investigation to focus on an Irish socialist group. At the same time, Sam's visions of the future suggest that he may have suffered brain damage, affecting his higher reasoning, from having been in a coma for so long.
