A dead asset manager calls Chief Prosecutor Reuther on the scene. Julia Schröder and Alexander Witte conduct the investigation behind the scenes of an investment company. Sebastian Fuchs was stabbed in the park at a late hour. A robbery seems to be eliminated. As Reuther the widow Dr. Isabel Fuchs-Eschenberg delivers the death message, he finds that their marriage was obviously not carefree. This was not least due to the tense relationship between Sebastian Fuchs and his mother-in-law Hermione Eschenberg. Isabel's mother seems to have had a problem with the fact that her now deceased husband had given Sebastian the management of the Family Office. Sebastian's petty-bourgeois origin obviously did not fit into her worldview.
The relationship between Hermione Eschenberg and Gerlinde Fuchs, the victim's mother, and their partner Bruno Schreiber, who is not a blank page with the police, was correspondingly tense. Investigations into the victim's professional environment finally lead the commissioners to Christian von Buchloe, who supports the Eschenbergs in various sustainability and charity projects. He attended a meeting with Sebastian Fuchs on the day of the crime, but his statements raise questions. It is quickly clear that this complex murder case can only be resolved if Reuther and the investigators succeed in reconstructing the exact course of the crime evening. The episode is available a week before the broadcast in the ZDFmediathek.
