The Second World War became history, but many of its secrets have not yet been revealed. Modern historical research on war suffers from incomplete data. Moreover, these data are not lost, they are still classified in the Russian archives. Along with the question: “Why is this data classified?”, The film addresses such seemingly obvious and sensational questions: What kind of war was the Red Army preparing for at the end of the 30s of the last century? Who Started the Second World War? The viewer will undoubtedly be interested in the views of the hero of the film - V. Suvorov, a former GRU employee who fled from the USSR and was sentenced to death in absentia - and his opponents.
