There is a serial killer on the loose in the tiny Yorkshire village of Holme Bridge. The community is gripped by a string of violent and brutal murders. Suspicion is flooding the town and the police are baffled. CIDs newest recruit, Scott Dempsey, is convinced they are all linked.

Meanwhile an amnesiac somewhere across town struggles to get to grips with who he is and what he's become, but does he hold the secrets to the killers identity?

Justifying the murders by his own faulty logic, the killer knows he must bring his rampage to an end in one ultimate climax. Can Scott solve the case before time runs out, and realises that he himself, is being used as a pawn in the serial killers game?
