Commissioner Jeanette Chilberg has no time to breathe. Firstly, we urgently need to find our son, who disappeared just when a sadist is operating in the capital, killing teenagers. Secondly, to identify the sadist himself, despite pressure from his superiors, who strive to freeze the investigation. Thirdly, to deal with a new series of murders, because someone has decided to brutally settle scores with men who in the past were put on trial for child abuse, but were never punished. And finally, fourthly, to understand what her fragile and amazing connection with psychotherapist Sofia Zetterlund brings to her. Sofia will have to decide whether to help the investigation by compiling a psychological profile of the maniac. She also has more important tasks - to help two girls, whose lives are disfigured by pedophile rapists, to penetrate deeper into the memory and soul of the mysterious Victoria Bergman and find out what happens during her own memory lapses, which leave behind strange, ominous traces.
