"Shadow Army Fighter," A. Agafonov, who went through all the horrors of the Lubyanka dungeons and the hardships of the Gulag, talks about how he happened to get there - a participant in the French Resistance and the underground anti-fascist struggle in Nazi Germany, a prisoner of Buchenwald. This is the story of a man whose iron will and irrepressible thirst for life helped not only survive, but also preserve human dignity, where people simply "grinded" with millstones of Stalinist dungeons.
