In tranquil Pöllau, Moritz Eisner (Harald Krassnitzer) and Bibi Fellner (Adele Neuhauser) have to solve the violent death of a man from Africa. There are no papers or clues as to the identity of the victim, who was found dead in the local quarry. His body was apparently to be disposed of there. The Viennese commissioners take on the operator Thomas Reuss (Martin Niedermair). The day before, he absolutely wanted to carry out a demolition – allegedly to meet official requirements. A trail also leads to his brother Albert (Andreas Kiendl), who worked as a doctor for aid organizations in West Africa and now runs an escape center at home. The investigators encountered a wall of silence among the residents.
While Eisner and Fellner grope in the dark, the autopsy brings a shocking result: the dead man is infected with Ebola! A disease commando immediately moves in, declares a state of emergency and quarantines the entire village. In the midst of the Ebola hysteria, Major Eisner and his colleague Bibi have to keep a cool head. The more they learn about the dead man and the background that led him to Austria, the more threatening the case becomes. Anyone could have contracted the deadly virus, including investigators. The fact that they continue their work puts both of them in great danger. To this day, it is impossible to prevent Ebola epidemics from breaking out in Africa.
The Austrian "Tatort: Virus" shows how justified the worldwide fear of the deadly fever is: A single infected person can be enough to bring the disease to Europe. In Styria, Moritz Eisner and Bibi Fellner investigate under correspondingly difficult conditions: Because a murder victim carries the pathogen, hysteria breaks out. Plague squad, quarantine and suspected cases - there is a state of emergency in the province. The television thriller cleverly leads the exciting case to a moral as well as political topic: It is also in our interest to fight the epidemics in poor countries with all our might.
