Chief Inspector Faber is back on duty, but his job as head of the homicide squad is gone for now. And prosecutor Matuschek wouldn't mind if nothing changed. Faber's colleague Rosa Herzog is now taking over the management on an acting basis. Chief Inspector Jan Pawlak, on the other hand, apparently has little interest in his job. Instead, he prefers to have fun in Alkim Celik's betting shop "Mutluluk" (Turkish for "luck"). When Celik's brother-in-law Lukas Becker is found dead, the "Mutluluk" suddenly becomes the focus of the investigation. An old acquaintance of Faber's is now back on the scene: Tarim Abakay . This time Faber doesn't want to let him get away with it. But his sleuthing doesn't remain without consequences for long: Faber is intercepted by Ira Klasnic and her two armed companions in the parking lot in front of his father's nursing home. Did Abakay send them?
