Stubbe is making optimistic plans for his upcoming retirement when a new case wrenches him from his thoughts. Realtor Tim König has been found bludgeoned to death. The investigations lead the inspector to the no-holds-barred fight over a district in Hamburg. The murdered realtor was known for unscrupulously ousting long-standing tenants from their apartments. Given the area of conflict between housing shortage and exploding real estate prices, almost any of the oppositionists in the district appears to have a motive. The attention of the police is drawn to activist storekeeper Karl Beck. The murdered man’s unsympathetic boss, Peter Fährmann, could also have a motive. At the crime scene, Investigator Tina Rosinsky meets her old friend Susanne Lorenz, who obviously has something to hide. As Stubbe tries to decipher König’s strangely disengaged life and find out what Susanne Lorenz and her dubious partner Dirk Darmstädter are up to, disaster is imminent. At Stubbe’s house, all signs are pointing to change: his daughter Chrissy is looking for a new place to live, and his lady friend Marlene also has a surprise up her sleeve.
