Drama series about Sam Tyler, a Manchester detective who suffers a near-fatal car crash and wakes up in what seems to be 1973. Sam encounters the young incarnation of Tony Crane, a nasty villain he put away in 2006. He realises he is faced with the chance every copper dreams about - stopping the killer before he kills. Sam fears that since his car accident in 2006, Crane has been released and has found his way to his hospital bedside where he is exacting his revenge on Sam's vulnerable body.
