District Inspector Pokorny was transferred some time ago from Vienna to the fictional Upper Austrian town of Mühlstadt after assaulting a suspect while on duty. There, as he says, he has to deal with "idiotic scoundrels who steal each other's chickens." Police officer Janisch was given a quick trial and sentenced to seven years in prison for robbing the post office in Litzelsdorf. His colleagues do not believe he is capable of such a crime and try to catch the real perpetrators. At the same time, they have to deal with a multitude of other cases.
