On Mother's Day, May 1945, an uprising against the German invaders broke out in Prague. The young husband has just enough time to congratulate his wife Miluška, who just had a baby, get armed and take his position at the barricades. German soldiers break into the apartment where his wife is alone with the baby. One of them likes the woman and she is saved from his rude advances only by the fact that all the people from the building are driven into the basement. Her little daughter's milk bottle breaks and Miluška is upset. A fire breaks out in the house, the Red Cross intervenes and the Germans are forced to let the women leave the basement. A German soldier throws a hand grenade after the young woman and she falls on the swaddling clothes together with her child. The child shows no signs of life. But inside the shelter a nurse takes care of the mother and realizes the child is alive. Miluška's joy joins the overwhelming feeling of happiness spreading among the people who have just discovered that Prague has been liberated.
