In Munich's Bahnhofsviertel, Commissioners Flierl, Neuhauser and Schaller inspect a body in eye-catching 70s clothing. Schaller immediately feels reminded of the neighborhood legend of that time: Gustav Schmidinger, the „ godfather " of the station district. But the dead is a common petty criminal. Schmidinger was one of the first to consistently establish prostitution and gambling in the Bahnhofsviertel. So Criminal Councilor Zangl knows him very well. At that time, Zangl fought bitter battles with the „ godfather ". Schmidinger, he teaches his subordinate commissioners, has lived in California for 30 years. Schmidinger's ex-wife Katharina knows this better: The „ Godfather " is back – and is claiming his terrain again.
The commissioners immerse themselves in the history of the station district of the 70s and early 80s, a strictly ordered world with the „ godfather " Schmidinger as a universally respected sole ruler. But these times are over. In addition Schmidinger's absence has shifted the balance of power. Claims are made, for example by Dirk Ascher, the owner of the laundry in the district, who ran the business in his sense during Schmidinger's absence. Zoja Kodraj, the head of a local nursing service, also plays an opaque role. Her friend Sahin owns the sports betting office and is angry that he has to vacate it. After all, Schmidinger's son Felix is not good at speaking to his father. But Schmidinger has to be seen if he wants to conquer his neighborhood again.
A doppelganger is quite practical, the commissioners find out. In this case, the commissioners soon lose their heads and collars. Zoja has Harald fidgeted on her long line. Schaller is on the network of the extremely attractive ex-wife of Schmidinger, who fights an extremely erotic fencing fight with him. Only Angelika keeps a cool head here and can only be briefly irritated by Schmidinger.

Commissioners Flierl, Neuhauser and Schaller uncover a supposed accident as murder. The victim was run over three times. The determination is difficult. The well-dressed murder victim does not carry any papers with him, labels of his tailor-made suit are removed. Chief Criminal Officer Zangel does not consider the matter to be worth investigating. Commissioners should rather digitize files. The commissioners secretly investigate. A first trace leads to a young tax advisor. Fidelius Aubacher immediately seems to be taken with Angelika Flierl. Angelika initially thinks this trail is cold, but later she will find Fidelius adoptive parents. The pathologist Dr. Spawner finds a striking liver stain on the dead and sewn in a tailor-made suit for 25,000 euros in cash.
Why did this man take the bus to the crime scene? Schaller learns more about the custom suit and thus about the victim, an Italian, about an old acquaintance, the tailor Kirschhuber. It soon turns out, that you are dealing with the Italian mafia and asks Commissario Quehenberger for help. In this case, Schaller becomes a bus driver, Harald suddenly struggles with a tough job killer, and Angelika almost falls in love with a witness to be interviewed – so that the three can get behind the circumstances of the mysterious murder.
