Parts of a man's body are found in an animal trap at the scene of the crime at a country estate near Kiel. This man was a member of a hunting party and everything indicates that militant animal rights activists are behind the murder. But Borowski soon finds out that even the hunting party there seems to have something to hide. This estate was deliberately chosen by the hunting party. Bears have been bought and now the aim is to illegally hunt bears here undisturbed.
