Nasir al Yasaf, the fifth son of the Emir of Kumar, leads a glamorous life in Munich. Protected by his diplomatic status, the young man takes every liberty: fast cars, extravagant parties, drugs. And the police stand by and do nothing. When Nasir's expensive sports car once again races through Munich, ignoring every red light & stopped only by police blockade, the body of his friend Karim is found in the passenger seat. Batic and Leitmayr are tasked with solving Karim's murder, but their hands are tied when it comes to their investigation. Batic rages, Leitmayr urges "diplomatic" action. But to their amazement, the Emir's son cooperates.
