When it comes to inheritance, suppressed feelings and hidden truths come to light: In their seventh case, inspectors Franziska Tobler and Friedemann Berg get deep insights into the dynamics of a wealthy Freiburg entrepreneurial family. The suspicious fall of the 78-year-old factory owner's widow Elisabeth Klingler calls the inspectors Franziska Tobler and Friedemann Berg into action. Klingler had just announced a change in the will to her daughter, her son, her granddaughter and the notary: after her death, the family villa should go to her supervisor Elena Zelenko. A shock for their children, who react with vehement indignation. Only when their mother is already dying do Gesine and Richard find out that Elisabeth Klingler and Elena Zelenko had secretly married.
Unlike their niece Toni, they don't want to accept this fact. Especially since it is now about more than just the villa. Torn between grief, the feeling of being rejected and fear of the financial consequences, the duped heirs present the inspectors with various clues as to Zelenko's involvement. Franziska Tobler and Friedemann Berg investigate, but also keep an eye on the family members. Especially since they found out during their investigations that the Klinglers and Elena Zelenko had a common past, the shadow of which weighed on Elisabeth Klingler.
