The body of the executive Thomas Loose is recovered dead from the Rhine. He was apparently very drunk and, according to witnesses, balanced on a quay wall from where he fell to his death. Corina Loose ( Liza Tschirner ) does not believe in the police accident thesis – her husband never drank more than two or three beers. A new order for the Fuchs & Kilali detective agency! While Anne ( Lina Wendel ) and Youssef ( Karim Chérif ) are researching the business lunch on the eve of Loose's death, Simone Papst ( Jasmin Schwiers ), Youssef's wife, is also faced with a new task: Her sick father Reinhard ( Günter Barton ) asks her to take on a short-term job in his real estate company.
When Anne and Youssef find out that Thomas Loose was employed by Simone's father as a buyer in the company empire, they use Simone's new sphere of activity: Anne is her personal assistant at Thomas Loose's workplace. Loose had only been with the Pope company for a few months and was pursuing a tough austerity course. Did he make enemies with it? Anne and Youssef discover in their investigations a well-kept secret in Simon's family, which is now coming to light – with far-reaching consequences.
