Code 37

In her private SM club, Sonja Raemakers, alias Mistress Soraya, is mutilated by an unknown person with a knife. There are no traces of a break-in, and the only ones with a key to the club apart from Sonja are her boyfriend Yves and the security guard Alek. When the latter has no alibi, he quickly becomes the prime suspect. He himself, however, draws attention to one of Soraya's regular slaves.
