The plot of the film is based on real events of the Great Patriotic War. When the Nazis occupied Crimea, the actors of the drama theater of the city of Simferopol entered the underground group Sokol. The activities of the underground members were diverse: they put up leaflets with information from Soviet Information Bureau, compiled maps showing the strategic objects of the enemy, and supplied the partisans with medicines. On April 10, 1944, 3 days before the liberation of Simferopol, the underground members died from enemy bullets — they were shot on the outskirts of the city.
