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.

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.

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.

Sam learns that an operation is to be conducted on him in 2006 to try and revive him from his coma. However, he believes that to return to the twenty-first century, he has to betray his colleagues in 1973 - but can he regard them as real or imagined?
