A headless male body is recovered from the Spree, whose identity is difficult to establish. A little later, Nina Rubin (Meret Becker) is being followed by a young woman. Julie Bolshakov (Bella Dayne) tells the detective that she witnessed a murder and asks Rubin for police protection. She knew the dead man from the Spree, he had revealed to her that her husband Yasha (Oleg Tikhomirov) is a leading member of the Russian mafia in Berlin .
Rubin decides to help the young woman and initiates the crime director (Nadeshda Brennicke). Julie wants to be included in a witness protection program if she can produce incriminating material about her husband in return. However, contact with Julie puts Rubin in a dilemma, because from now on she has to keep Karow (Mark Waschke) out of the investigation so as not to endanger the young woman. Karow investigates the identity of the dead man, but senses more and more that his colleague is hiding things from him. Trust has been a thorny issue between the two from the start, and Rubin's behavior hurts Karow — especially since they've also become closer privately. All the more the old problem breaks out again. In her latest case, will Nina Rubin be able to free Julie from the clutches of her crime family?
