A mysterious caller offers Sam a chance to return to the present, but a confusing set of circumstances makes him wonder whether he wants to go back.

Sam is accused of murder.

Sam and Annie go undercover to solve the case of a murdered airline stewardess and end up being invited to a swinging '70s party.

CID is chasing a notorious cop killer and Gene is going undercover as part of a departmental sting operation to catch the villain red-handed during a train heist. All Sam has to do, Morgan promises, is one more job and he can 'come home'. Sam's presumptions about his past, future and his very soul unravel in a heart-stopping climax.

Sam is woken in the middle of the night by Gene - drunk, and apparently having killed someone. While the evidence stacks up against Gene, Sam tries to prove his Guv's innocence, watched by DCI Frank Morgan from Hyde division.

Heroin has hit the streets of Manchester and Gene wants culprits. When investigating the murder of a Ugandan Asian man, Sam battles against the bigoted reaction of his DCI. His sympathy is further stirred by messages from Maya, his Asian girlfriend in 2007.

The body of a young woman is found in wasteland. The investigation takes the team to suburbia, where a local car dealer is throwing private parties, employing the make-up girls to 'help out' when the wife-swapping begins...

When a bomb warning is reported, A-Division goes on red alert. The IRA has begun its mainland bombing campaign. Now the terror has arrived - or has it?

Despite eerie visions of 2006, DCI Sam Tyler remains in the 70s - where he encounters the young incarnation of a nasty villain Sam put away in 2006. He sees the chance every policeman dreams about: stopping the killer before he kills.

With his mentor presiding over an armed robbery investigation, DCI Gene Hunt is keen to show off his team. And with his own (future) mentor working with the team as a lowly DC, Sam too tries to be at his best.

As the team investigates a murder linked to a crime syndicate, Sam is finally accepting the world of 1973 and believes that he can deal with anything that it throws at him... until he comes face to face with his 29-year-old father, Vic.

The death in custody of small-time drug dealer Billy Kemble pits Sam against the whole of CID as he tries to uncover the truth of what happened in the cells.
