The brutal attack on an inconspicuous software company confronts Chief Prosecutor Bernd Reuther with a dangerous case in the area of organized crime. Jens Schubeck, one of the company's managing directors, was murdered in the raid. For Reuther, Chief Commissioner Kerstin Klar and Commissioner Max Fischer, the question arises as to why Schubeck's business partner Dominik Winder survived the incident. Dominik Winder has also behaved very strangely since the raid, which is not hidden from his wife Tina. Did the two company bosses mess with the wrong people? Alexandra Schubeck, the dead woman, also puzzles the police. She seems to be very afraid of something.
Does she know more than she wants to admit? The case becomes even more puzzling when Dominik Winder suddenly receives support from Paula Olafson, a notorious lawyer in the Hamburg underworld, who has recently returned to her hometown Wiesbaden. Max Fischer recognizes Olafson's shady companions Eric Rittmann and Hector Peschke from his time as a covert investigator in Hamburg. Without further ado, he therefore suggests Reuther to return to his tarn identity at the time, to feel the two on the tooth. Kerstin Klar has not had a good feeling from the start. In fact, Fischer soon gets into great danger with his risky undercover use.
To clarify the case, not only Reuthers razor-sharp combination gift is required, but also a crucial note from legal doctor Dr. Judith Engel.
