The blockade of Leningrad is one of the symbols of human resilience, but at the same time it is the clearest example of inhuman cruelty. The author of the documentary "Blockade" chose the chronicle of the war years from the Russian and German archives as a tool for narration, adding to it only the music that sounded in those years, archival recordings of Leningrad radio reports, and the sounds that accompanied the residents of the city throughout the days of the blockade. Is it possible to heal the pain caused? How not to repeat the tragedy again?
