In 1994 two younger twins are discovered brutally murdered in a summer season cottage. A variety of clues factors within the course of a gaggle of younger higher class college students from a close-by boarding faculty, however the case is closed as an area outsider pleads responsible and is convicted for the murders. When the case finally ends up on Carls Mørck’s desk 20 years later, he quickly realises that one thing is very fallacious. As Carl and Assad begin investigating the case, they’re led on to an outdated emergency name from a determined woman who appears to know the secrets and techniques of the murders. Quickly they’re plunged into an intense seek for the woman, Kimmie, who has been lacking for the reason that murders occurred. However Carl and Assad aren’t the one ones making an attempt to trace her down because the woman’s testimonial is of nice hazard to a gaggle of influential males on the prime of society who will do all they will to maintain her silent.
