Olaf Liebermann breaks down at a neighbourhood party in Blauregenweg. Apparently a poisonous substance was poured into his canned beer. Heldt literally investigates on the spot. As Nikolas Richter's lawyer, he moves in undercover with Franziska Lagura, who rents out her attic. Heldt is sure: "It was one of the neighbours. After all, this is not the first attack on the cozy early pensioner, as his wife reports. Claudia Liebermann is a midwife and, just like Heldt, is a member of the "Never steig ab" football fan club. She tells Heldt about a sawn-on ladder and a manipulated power cable in the lawnmower. Also the attack with slug pellets in the beer goes off lightly, as Dr. Holle states. Olaf believes in accidents, but Heldt, Chief Commissioner Green, and prosecutor Bannenberg do not trust peace. Someone is targeting Olaf - but who? And above all, why?
