The height of the Great Patriotic War. With the arrival of the invaders, the head of the pharmacy, Anna Korzun, establishes contact with the partisans and now regularly transmits medicines and information to them. Every day, risking her life and the lives of her sons, surrounded by traitors who are ready to go to the police at the first danger, this selfless woman does not doubt for a second the correctness of the chosen path. And when danger threatens to interfere with her work, she and her sons go into the forest to the partisans.
