The manager Josef Micklitza appeared at the Dortmund police headquarters late in the evening, extremely nervous and soaked in the rain. He found a dead person with a gunshot wound on the port area. It is his financial advisor Claus Lembach, a heavyweight in the highly sensitive financial sector. While the Dortmund homicide commission is starting the investigation, the news of the murder startles the dead man's wealthy clientele, who have so far been spoiled by rich returns. Are their millions of assets in danger now or are they adequately secured by the private bank Roden? When the only witness is suddenly disappeared, his brother, the nightclub owner Micki, is the investigators' sights. The excessively drug-consuming half-world boss seems to have made contact with the murder victim's customers. Things get really complicated when Commissioner Jan Pawlak discovers that his missing wife is the main suspect's junkie sweetheart.
