Young Detective Constable Anna Travis joins the team led by D.C.I. Langton to investigate a series of gruesome murders of young women, which first began eight years previously. All the victims were prostitutes and all killed in the same way. Then a seventh body is found but this is the corpse of a student, though a vital piece of evidence links her death to the others, involving a house in Manchester where Alan Daniels, a popular young actor, grew up. Anna goes undercover to get to know him better but finds herself getting emotionally involved.
