The body of the Polish pimp Jerzy Zaorski is found on a motorway bridge. Semir and Tom investigate and suspect that the prostitutes that Zaorski exploited could have something to do with the murder. Janina, a young prostitute, is particularly suspected, but an alibi provided by the pastor of the motorway church exonerates the women. When Zaorski's brutal brother Waczlaw arrives in Germany to seek revenge, the police must prevent him from finding the murderer.
