While a tragic accident occurs in a chemical factory, the two investigators Moritz Eisner (Harald Krassnitzer) and Bibi Fellner (Adele Neuhauser) appear slightly overdressed at the birthday party of their supervisor Ernst Rauter (Hubert Kramar). The mood is good, but Rauter misses his godchild Roswita (Emily Cox) at the party. Her husband Helmut (Eugen Knecht) excuses his wife because she still has work to do. But then it turns out that Roswita is the victim of the chemical accident. A defective protective suit could not protect them from the escaping, highly aggressive hydrofluoric acid. Finally, the ten-month pregnant woman succumbs to her injury. Rauter is deeply shocked and asks Eisner and Fellner to investigate the matter.
It soon turns out that the protective suits are supplied by a company that belongs to the Wendler Group. Apparently, a larger proportion of the suits do not comply with the required safety regulations. The protective suit business is managed by Sabrina Wendler (Maria Köstlinger), a self-confident, cool woman who denies any responsibility for the accident. Her husband Peter (Anian Zollner), heir to the Wendler works, has been in closed custody for yearsPsychiatry. He was convicted of attempting to murder his wife and is now about to be released. In his place, Dr. Viktor Perschava (Michael Masula) the company. Sabrina Wendler would like to sell the group as soon as possible in order to emigrate with Perschawa, who is also her lover.
But he increasingly distances himself from this thought. In the meantime, the young widower Helmut Marder has also found out about the Wendler Group. He wants to hold those responsible for the death of his wife accountable, but initially only meets the secretary Elisabeth Schneider (Johanna Mertinz), a veteran of the company and loyal to the Wendler family. Shortly thereafter, Viktor Perschava is found shot dead. For Eisner and Fellner, the actual investigative work now begins. The internationally renowned director Robert Dornhelm tells the story of the rise and fall of a family of manufacturers, of the loss of values in the new economic world and takes archaic feelings of revenge and retribution into account.
Harald Krassnitzer and Adele Neuhauser are in top form alongside top-class episode actors such as Emily Cox and Anian Zollner. They face the thicket of guilt and atonement with a cool mind.
