The detectives are dealing with an unusual case: the husband of successful real estate agent Birgit Leibold reports his wife as kidnapped. Detective Beissl is skeptical, wondering whether Klaus Leibold himself might be involved—especially when it turns out that the agent's facade is more appearance than reality: Birgit Leibold is broke! Is the husband now trying to get back on his feet financially by staging a fake kidnapping?

The unusual ransom sum leads the detectives' investigations into the real estate world. A secret deal between the agent and her best friend, Veronika Berger, presents the detectives with a mystery. But then the agent's former employee, Quirin Steiner, becomes the focus of the investigation: a bitter dispute rages between him and Birgit over commissions and reputation.

Golf coach Toni Brendel is found dead on the Berchtesgaden golf course. Everything points to murder. Toni Brendel, who wanted to influence the future of the golf club with ambitious construction plans, did not have only friends. Club president Julius Greiner, who wanted to prevent Toni's plans and whose reputation was damaged by Toni's slander, is just as much a suspect as Toni's betrayed wife Pia Brendel and his mistress Franziska Schachtner.

In the course of the investigation, many motives and clues emerge, but there is no evidence. Only after Toni's past has been examined more closely and Beissl has resorted to an unconventional criminalistic ruse can the perpetrator be unmasked.
