Russian propaganda film. In 1945, the Second World War has not yet ended, but large-scale work is underway on the territory of liberated Belarus to clear the land of the legacy of war – unexploded mines and shells left in the ground at the site of military operations. OSOAVIAKHIM detachments are created from among teenage volunteers. After completing only a week’s training, young girls and boys are sent to personally demining places where fierce battles had recently taken place.
