Young Adam Moser has a fatal accident on his motorcycle at night. But the death raises questions and ultimately leads inspectors Ivo Batic and Franz Leitmayr to Munich's Hasenbergl. Here the dead man lived with his girlfriend in a small bungalow in the middle of the anonymous high-rise buildings in the district. Old Hackl lives in the house next door, a well-known troublemaker whose anger potential is notorious not only among the Munich police: Did he also have something against Adam? Enough that he had to die? As always, the old Grantler makes things difficult for the authorities and violently evades enforcement. The mood between Franz and Ivo is at its lowest point while a large-scale search for Hackl begins. There seems to be more hidden behind the cold, high facades: a world full of frustration, narrowness and envy.
