Flora Hansen calls herself a spiritualistic medium and for many years she has made a living making believe that she can talk to the dead. One evening in August she reads on the news bills that there has been a terrible murder at an institution for young women with destructive behavior. Flora Hansen decides to call the police and claim that she has made contact with the spirit of the dead girl. The technical investigation without any doubt singles out one of the inmates, a “good”, quiet girl, who ran away from the institution on the night of the murder, as the perpetrator. When Joona Linna starts looking into her past, it appears that she has not always been that very good.
