Psychologist Frieda Klein's most personal case: Everyone she loves is in danger. The body of a man is found beneath the floorboards in Frieda Klein's living room. He is the detective that Frieda had assigned to investigate her stalker, Dean Reeve. She is convinced that Dean is the murderer, but the police do not believe her. Then, events suddenly spiral out of control: Frieda's niece is kidnapped, someone assaults her former mentor, and then her friend Josef's young son disappears without a trace. Clearly, someone wants to intimidate her. However, the crimes do not bear Dean's signature. Who is the unknown person imitating him? And who will be their next target? Time is running out.
