Moritz Eisner (Harald Krassnitzer) and Bibi Fellner (Adele Neuhauser) get a special assignment that leads the Viennese investigators to a remote corner of Carinthia at the foot of the Grossglockner. Hubert Tribusser (Christoph von Friedl), the junior boss of a timber company of the same name, is missing there. His father (Johannes Seilern), a friend of the Vienna police chief, does not want to leave the investigation to the local police station. As soon as Eisner and Fellner arrive in the Mölltal, the search is over - but not the unpopular case. Sawmill workers found "something" from Hubert in the kiln ash: a titanium implant from his shoulder joint. The find points to a crime that someone tried to cover up.
A first suspicion falls on the Environmental activist Holzer (David Oberkogler), against whom the Tribussers have filed a lawsuit for defamation and who is said to have had a heated argument with Hubert on the evening of the murder. In the search for the perpetrators and the motive, the Viennese investigative duo uncovers that the dead man was anything but a saint. Hubert took what he wanted: money from the company treasury, countless affairs and even the wife (Caroline Frank) of his own brother Klaus (Alexander Linhardt). The local police chief Alois Feinig (Karl Fischer), who Eisner knows from before, is involved in the investigation. He provides the Viennese duo with local insider knowledge, Asian wisdom and a promising lead. While Eisner thinks highly of his old friend, Bibi observes him with growing skepticism.
