Tatort S2017E03 - Eisner - 39 - Schock

Lieutenant Colonel Moritz Eisner (Harald Krassnitzer) and his colleague Major Bibi Fellner (Adele Neuhauser) want to prevent an announced double murder in an unusual case: a young man from a good family has kidnapped his parents and announces via internet video, first them and then himself kill. What sounds like an act of insanity is presented by David Frank (Aaron Karl) as completely "normal", because the medical student wants to point out social grievances with his spectacular action. According to his ingenious plan, the police should only find out what he is about in the course of the investigation and in front of the eyes of the Internet public. The fact that the kidnapper is always one step ahead of him is hard on Eisner.
In addition, the constitutional protection officer Gerold Schubert (Dominik Warta), who accompanies the case, gets on his nerves. And the investigator has to find out that his daughter Claudia's (Tanja Raunig) friend (Mehmet Sözer) is involved in the matter. The fact that parts of the student body sympathize with their fellow student David is obviously also very irritating for the investigators. The critical professor Sarah Adler (Mercedes Escherer), an expert on rampages, seems to know more about his motives. However, the former activist is not very cooperative.
