A killer is loose in a small Yorkshire town. The police are on the hunt, led by Detective Inspector Richard Platt and his team. The deeper they get drawn into the case, the more Platt believes that there's more to the killings than meets the eye.

Meanwhile, Melanie Foster - a girl locked away in Larksford House Clinic - is planning her escape. Wrongfully incarcerated, she's determined to find her parents, track down the person responsible and find out why she was hidden away.

But everything is not as it seems, and people are not who they say they are. Soon, secrets that have been buried countless years will be revealed with murderous consequences.
