This dramatisation of a 1983 real case from the police files of a seemingly boring man who carried out gruesome murders of equally unimpressive men in a most deliberate manner. He is credited to have killed at least 12 men. An ex-army cook with a short stint as a policeman and a civil servant invites young men to his apartment, makes them inebriated, kills them in various manners, and disposes of them in equally grisly ways.
