Oliver Bachmann was fatally shot in his communal garden plot. The team look into his plot neighbors, whom he hassled as 'Heckenpolizist' (society rules supervisor), notably Bruno Kaiser and Konrad Tauber, whose wife Sofie had an affair with Bachmann. Penniless student Felix Reiter lived secretly -against the rules- in his recovering grandmother's plot cabin, and smells a blackmail opportunity. Blood traces lead to another secret, about an injured illegal construction laborer bleeding to death after a site saw accident.
