Youth psychologist Julia Egger causes a traffic accident, seriously injuring a man, and drives away in panic. Her explanation that she was deliberately forced off the road by an SUV initially sounds unconvincing to Borchert and Dominique, especially since Julia has a history of drunk driving.
During their tour, Werner Träsch and his colleagues Ralle Schieber and Tarik Büyüktürk arrive at a housing estate where the businessman Waselitzki draws their attention to graffiti. Waselitzki plans to rent out the apartments in order to then rent them out again at a higher price. Träsch and his colleagues want to prevent this with all their might.
