Dealer and pimp Serkan Bürec was shot dead in Nora Dalay's neighborhood. He was considered the right hand of the shady businessman Tarim Abakay. For Chief Inspector Peter Faber, everything indicates that there was also a witness at the crime scene. But she has disappeared without a trace. Patrol officers Rainer Polland and Paul Klose don't like the fact that the homicide squad is now investigating in their precinct. Nora Dalay knows the impulsive Polland well. The two used to go on patrol together. And Polland's wife Sonja is also no stranger to the area: The ex-prostitute is now committed to street girls and helps them where she can. Chief Inspector Martina Bönisch quickly finds a good connection to her.
But does she also know where the missing witness is? Meanwhile, Daniel Kossik is asking around among the men who are waiting for their next job "on the workers' street". The victim is said to have had a recent argument with one of them, Marek Bojanov. Was it about the horrendous rents for the run-down accommodation that its boss Tarim Abakay collects from the immigrants?
