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.
