The Giesingen football club has lost again. Commissioner Neuhauser and colleague Flierl pour the game into a pub and promptly encounter a dead man. They inform Schaller. In the old working-class district, fans of the „ blue " rage. But the commissioners are faced with a wall of silence when asked. Nobody reveals the other here. However, at least two people have a motive: the wife Leana and Kumpel „ Breitner ". The host of the „ Kronenstüberl ", Gusthoff, is also behaving strangely. He always eludes the surveys. The three commissioners are first sent to their superior Zangel, who once again thinks that the commissioners should stay away from the case.
Driven by the realization that the murderer is hiding in the crowd of fans, the trio agrees to stay in the neighborhood until it has arrested the murderer. Harald persuades the local police forces to record the personal details of the fans – four boxes of beer and soccer tickets confirm his arguments. Then he takes on the buddy of the murder victim, „ Breitner ", who is annoying the pub guests with verbose game analyzes. Flierl deals with the dead's wife, Leana Reinl. Flierl is sure that the woman is lying. Schaller deals with the witness of the murder, Ms. Birgel. All in vain. The laws of this district are clear: the police have no business here. Nobody gives a hint. Reinl even makes no secret of the fact that Flierl cannot suffer.
But the commissioners quickly learn how to take the Giesinger. In the end, Flierl sits with Leana in a very informative conversation, Schaller learns what he is like about egg liqueur with Ms. Birgel, and Harald uses his contacts to Jessy and Maiki and ensures „ Breitner " in the standby bus. The next morning, the three commissioners resolved the case with their own resources, without having left Giesing once. Full stadiums, closely related fans: During the shoot of the eleventh case of „ Munich Murder ", the Corona pandemic was not yet apparent. Actor Marcus Mittermeier was in his element in the milieu: In his youth, a promising football career started for him until an injury put an end to all dreams.
Today he looks after the benefit teams who kick for his aid project.

The commissioner trio Schaller, Flierl and Neuhauser are investigating an explosion with fatalities in a allotment garden settlement. The explosion was not an accident, but the gas pipeline was manipulated. Celine Pope appears worried at the scene. Because she and especially her new friend Karim use the affected hut, which belongs to Celine's father Oliver Papst. Celine's concern for Karim is well founded. She is pregnant, but doesn't want to know anything about her ex-boyfriend Patrick. Patrick absolutely wants to maintain the relationship, also because of the child, and feels Karim all the more as a rival when he accepts the child and is looking forward to it. Patrick's jealousy culminates in the kidnapping of Karim. Moreover, it soon seems that Celine's father, who knows Patrick well, is playing a crucial role here.
The commissioner trio gradually discovers a tangible love and family drama behind the gas explosion in the allotment garden. Meanwhile Angelika Flierl also fights in Liebesdingen. She is on an internet platform, and only when she meets one of the candidates does she become puzzled and notice that she has been a police-known right-wing agency. Flierl gets violent trouble with criminal superior Zangel. But Harald and Schaller are firmly committed to their colleague.
