Everything indicates that the young police officer Rebecca Kästner committed suicide in her apartment the evening before: drugs, custody dispute, excessive demands. But when Karow finds her four-year-old son Matti frightened in the garden, he begins to have doubts about the suicide. What mother does that in front of her child?

Before Karow knows it, she is at his side to investigate this case. Back on the road at 62?

During the investigation into Rebecca's death, the detectives also come across connections to the right-wing scene, which Bonard quickly suspects is a large right-wing network.

A dead man died in his house from multiple stab wounds, but there are no signs of break-in or evidence of robbery. Initial investigations also lead nowhere until Karow comes across a hidden door in the house. What the two inspectors find there takes their breath away. Bonard and Karow immerse themselves in the Vietnamese world of Berlin. You meet the veterinarian Dr. Lê Müller from Charlottenburg. Müller knows the dead man from before and knows more than she lets on, but she doesn't trust the police. The LKA officer Pham Thi Mai puts Bonard and Karow on the trail of a young Vietnamese woman - is she the woman they are looking for? The investigation leads Karow to a pagoda in Lichtenberg, where the souls of the ancestors have their place. However, the community's cultural center is under acute threat of demolition. This hits a sore spot for Karow. In order to solve the challenging case, Bonard and Karow also have to grow together emotionally as a team.

In broad daylight, a man is shot dead from a great distance by a sniper in the center of Berlin, near the Friedrichstrasse subway station. Susanne Bonard and Robert Karow are under pressure - and under observation: Preparations are underway for a major state visit to Berlin and the Senator for the Interior is worried about the murder. Public Prosecutor Taghavi demands that the matter be clarified as quickly as possible.
