A couple therapist is found murdered in his practice. For Bernd Reuther, the question arises as to who might have had a motive to tear Frank Richard out of life. There is a trail of devastation at the scene. But there doesn't seem to have been a fight, the victim has no defense injuries. High Commissioner Alexander Witte suspects that the perpetrator was specifically looking for something. Victims and perpetrators knew each other well. Together with Chief Commissioner Julia Schröder, Witte tries to reconstruct the procedure on the evening of the crime. Patients report a recent dispute between Frank Richard and an unknown woman. Is there a possible motive here? Reuther goes to the theater to deliver the news of her husband's death to Lydia Richard. The set designer suffers a nervous breakdown.
She can't make sense of what's going on. Her daughter Mira, who is currently doing an internship at the theater, is also shocked. The commissioners' investigations lead to Hermann and Ulrike Kiefer. Frank Richard's therapy does not seem to have struck the couple living in separation. To make matters worse, the jealous Mr. Kiefer accuses the victim of having spanned the woman out of him. Has he now taken revenge on the therapist? Regular transfers from Frank Richard to Meike Sommer, one of his former students, will soon lead the investigators on a further trail. The more they find out about the victim, the more it becomes clear, that Richard apparently had some secrets from his family.
