Investigators Ina Zimmermann and Kim Nowak are called to a murder that took place in the apartment building of Kim's mother Monja Nowak. Her neighbor Lazlow Trimmborn was killed with a gas pistol. The website "Connewitz helps" could provide information about the murder. Lazlow used this forum to hang out with pretty women. His female stories may have something to do with his death. But Monja also seems to be involved in the case. Kim notices strange tensions between her mother and her boss Ina. Both women are far from benevolent, but they keep a secret.
