After her shift, trainee Annabelle is pushed in front of a moving truck at a bus stop. She dies at the scene. Mavi breathes a sigh of relief because her mother does not have dementia after all. Meanwhile, Robert is worried about Emmi, who is admitted to the hospital where the murder victim worked with stomach pains. While Mavi asks around in the hospital, Robert speaks to Annabelle's flatmate Zoe and her boyfriend Tobias. In her room, Robert finds secretly taken photos of the victim and threatening letters addressed to her. Did someone want to scare her?

When 42-year-old Sina Priemke is beaten to death in a forest, the trail quickly leads to the university where she taught as a lecturer in computer science. Shortly before her death, Sina listened to secretly recorded, obscene audio recordings between her superior, Professor Brenneisen, and a certain Melanie. This is why the professor is immediately targeted by investigators. As it turns out, all the students and Professor Brenneisen received these audio recordings at the same time. From whom? And who is the unknown Melanie? Neither Brenneisen, nor any of the students, nor Sina's brother André know her.

A burning boat drifts on the Spree in the middle of the night. The police find a burned body that is difficult to identify.

Early in the morning, a man is run over by a car. The emergency doctor called by a passerby can only confirm death - hit and run or murder? When Robert and Mavi arrive at the scene, it quickly becomes clear that it was not an accident. They are able to identify the dead man as Thomas Bülow, who apparently led a solid, middle-class life in Köpenick. Bülow and his wife Anita are expecting a child. Together with his sister, he worked as an heir investigator. Whenever someone dies without a will and no relatives can be found, they come into play. Did someone want to prevent Bülow from finding a distant relative? When Robert and Mavi come across bartender Eckhard Jablonski, who believes that Bülow cheated him out of his inheritance, Jablonski becomes the focus of the investigation.

Margot Ahrens turns up at the police station and claims that her missing 38-year-old daughter Diana is dead. Mavi feels sorry for the desperate mother and investigates the matter. Robert suspects that Diana Ahrens went on a spontaneous vacation. But Mavi comes across a number of inconsistencies when searching Diana's apartment and finds a flyer for a Dutch abortion clinic that Diana was apparently in contact with. While Mavi questions the neighbors and finds out that medical student Sebastian Hartung actually organized an abortion appointment in Holland, Diana's car is found at the train station. Robert and Mavi suspect that someone has staged her disappearance as a spontaneous vacation.

The body of Stella's physics teacher Torben Fendrig is found in the Köpenick prison, which has been empty for years. He had been locked in a cell and died of thirst there. Fendrig had only recently inherited millions. Are Robert and Mavi dealing with a ransom demand that got out of hand? When they find out that Fendrig wanted a divorce, his wife Marina comes under suspicion. At the same time, Robert and Mavi take a closer look at Fendrig's students. The formerly popular teacher had suddenly become a schoolyard terror. And Fendrig had his sights set on one of Stella's classmates in particular: Jörn Hankwitz. Jörn is part of the "roofer scene" and climbs illegally onto office roofs and factory buildings at night for an adrenaline rush. The higher and more dangerous, the better.
