Documentary and artistic research dedicated to the dizzying career and death of one of the prominent Nazi leaders - Reinhard Heydrich. The purpose of the study is to analyze little-known events associated with the German occupation of Czechoslovakia, to draw an analogy between the events of 65 years ago, which led to a huge number of civilian casualties, and the recent war in the Balkans. There are no fictional characters in this political action film; all the events described in the novel are based on based on strictly documentary material. The main core of the plot is the murder of the German protector of Bohemia and Moravia, Heydrich, by English saboteurs. There are still many uncertainties in the history of the famous sabotage, which led to tragic consequences... In the first part, much attention is paid to the occupation of Czechoslovakia and some SD operations carried out under the direct leadership of Heydrich. The second part is devoted to the preparation and conduct of the operation to destroy Heydrich, as well as the intrigues of British intelligence associated with it.
