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 and can only be stopped by a 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. You are not allowed to do anything. Don't even question Nasir as the prime suspect if he doesn't want to. Let alone examine the car by the police. As a diplomatic vehicle, the location of the corpse is extraterritorial territory.
Batic rages, Leitmayr warns of "diplomatic" action. But to their amazement, the Emir's son cooperates. Together with Kumar's consul general, Abdel Saleh, he takes them to the place where Karim was shot dead and where he allegedly loaded his friend's body into the car to drive him to the hospital as quickly as possible. Karim was shot in front of the house where student Michaela Scheffner lives. She had a secret love affair with Karim and apparently knows more than she lets on. The role of Consul General Saleh also remains unclear.
Is he really interested in helping the German authorities solve the case? Or is he pursuing his own interests? As the evidence accumulates that the young Arab's death could be related to illegal business, the case takes on a new dimension. The trail leads to the Bavarian Ministry of Economic Affairs to State Secretary Baum, a hothead who hopes for career opportunities. Batic and Leitmayr get caught in the fire between politics, the judiciary and business. When the prince's chauffeur confesses to the crime, which allegedly involved drugs and debt, the case seems to be solved, at least for Chief Prosecutor Kysela. But Batic and Leitmayr don't believe in it. They mistake the chauffeur for a pawn and fight doggedly to bring the real culprits to light.
