Hans and the love of his life, Ines, have enjoyed a blissful week together after their surprising reunion. But Ines must leave Hamburg forever the following day. She is still in the witness protection program, which is why she and Hans had to part ways all those years ago. Hans, who is finally happy again, is in anguish, but their situation seems impossible to resolve. When Hans and Franzi are called to investigate a burglary at the apartment of their retired colleague Wilfried Schipper, no one suspects that this meeting will be very significant for both men.
