Donna Langford has spent ten years in prison for organising her husband's murder. When her daughter goes missing, Donna believes there can only be one man responsible. DI Tom Thorne worked on the Alan Langford case, so he refuses to believe that the man whose body was found in a burned-out car can still be alive. But when a prison inmate that he and Anna interview is viciously murdered, Thorne starts to understand that Langford is not only alive, but ready to get rid of anyone who could threaten his comfortable new life in Spain.
