Very nervous and soaked from the rain, the manager Josef Micklitza shows up at the Dortmund police headquarters late in the evening: he found a dead person with a gunshot wound on the port area. It's about his financial advisor Claus Lembach, a heavyweight in a highly sensitive industry. The news of the murder startles its customers: So far there have been substantial returns, are millions of fortunes now in danger? Or are they adequately secured by the private bank "Roden"? Why Josef Micklitza went into hiding on the night of the murder, his brother Micki cannot say either. The two brothers live in different worlds, but have never let go of their contact. Micki owns a nightclub and hardly tries to hide his drug use. Now Commissioner Jan Pawlak is watching him contact the customers of the murdered Claus Lembach. Completely unexpectedly, Pawlak meets his wife Ella during the investigation: the mother of their daughter disappeared over a year ago. Now he hopes that she will return home and that they can be family again.
