On the night of June 4, 2000, a 16-year-old girl in Falun witnesses what she believes to be a murder. The police are called to the suspected crime scene and soon a dog patrol finds a naked, dead and raped woman. The woman turns out to be 31-year-old Pernilla Hellgren.

In the fall of 2018, a woman claims to the police that three men have murdered and dismembered an acquaintance of hers. But when police technicians investigate the apartment where it all allegedly happened, they find no traces.
