Series 1

Sam (John Simm) has finally started to accept his new world and believes that he can deal with anything that it throws at him. Then he comes face to face with his 29-year-old dad.

The murder of a bookies clerk leads the team to Vic Tyler (Lee Ingleby), a small time gambler who unwittingly finds himself at the centre of the enquiry. Gene (Philip Glenister) is convinced that Vic is his link to nailing a new crime syndicate, the Morton brothers, and is prepared to put Vic's life on the line to get to them.

A stunned Sam finds himself having to embark upon an emotional journey as he has to protect his own father, firstly from Gene, but also from the Mortons.

Sam realises this is the time in 1973 that his dad left the family for good. Is that why he's here? To clear his father's name and stop him from leaving? If he convinces his dad to stay with the family will he wake up in 2006?

Sam starts to piece together a childhood memory that he has been repeatedly experiencing as a series of flashbacks. Making sense of these memories sees him start to uncover the truth about his father, and what really happened to his family - a truth that will change him forever.

The woman in the red dress from Sam's memory turns out to be Annie (Liz White). As a child Sam saw his father attack her in the woods when she tried to arrest him. This time, Sam keeps his 4-year-old self away from the incident and steps in himself to protect Annie. He discovers that his dad isn't the man he thought he was, and has in fact created the Morton brothers as a front for his own criminal dealings.

Sam faces a huge dilemma. If Vic stays, his family will discover the truth about him and he'll go to prison. But it could be the key to Sam waking from his coma. If he goes, no one will ever know what really happened, history will remain unchanged, and Sam will stay in 1973.

Sam lets his dad go and covers for his disappearance. As he heads off to the pub with Gene, Chris (Marshall Lancaster) and Ray (Dean Andrews), he wonders if he'll ever return to his own time. He admits to Annie that her presence means life isn't all bad in 1973.
