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.
