Political thriller "Dengler" centres around private detective and disenchanted former special investigator Georg Dengler. Even after quitting his job, he never abandons his personal quest for truth and justice.
In this episode, he is sent a prepaid mobile phone, then receives € 15,000 in an envelope and an anonymous phone call asking him to discover who shot Uwe Mundlos and Uwe Böhnhardt, members of a far-right terrorist cell.
Dengler believes the official line that they committed suicide, but needs the money, so he accepts the case. With the aid of Olga, an underground hacker, he begins to reconstruct the events that led to these deaths. Numerous inconsistencies are soon revealed and the pair are drawn into a dark world of neo-Nazis, state security agents, and fascist extremism. What they don’t realise is that they are already in the sights of powerful criminal masterminds.
