Drama series about a Manchester detective who suffers a near-fatal car crash and wakes up in what seems to be 1973. Sam's principles call into question the ethos of his whole department as he takes on a local gangster in an attempt to stamp out police corruption. Gene believes that criminals and the police can co-exist and that the streets are safer as a result, but Sam knows that in the future police corruption will irrevocably change the relationship between the public and the police.
