1941. A  Ukrainian town occupied by German troops, where the Nazis organized the Ghetto. Nearby lives the family of janitor Peter, who works in the Ghetto and has unlimited access there. Peter's son, Mykolka, constantly takes food out of the house, which the family lacks so much. The father beats the son, but it does not affect the boy's actions: he humbly accepts the frequent punishments and is silent about his motivation. A Jewish family Liberblum, who are living in  the Ghetto, learns about a Nazi-planned operation to send children from the Ghetto to a concentration camp. Parents are trying to save their son Jacob and daughter Raia from this. However, no one can help them except the janitor Peter but he refuses to help the Jews. Peter follow his son, who again brings out the food and makes a shocking discovery: Mykolka throws food over the fence of the ghetto to Raia Liberblum. The father reconsiders his son's behavior and decides to help the Jewish family, provided that he takes only one child out of the Ghetto. The Liberblum couple face a difficult choice - who to save?  Son or daughter?
