A group of women in the Warsaw Ghetto hears Nazis raid their building. Three women are Jewish: RACHELA, SONIA, and NELLY, who has a three-month-old baby named ZOFIA. Their friend ALINA is a Polish-Catholic smuggler. Nelly convinces Alina—who, as a Catholic, is the only one who can exit the ghetto—to smuggle her baby out a three-story bathroom window. Nazis storm into the apartment as Alina jumps out the window. Nelly quickly lowers her baby in a box as Nazis threaten to shoot the bathroom door. They shoot just as Alina catches the box and Nelly ducks for cover. Finding nothing, the men leave in search of more children to take to concentration camps as Alina, down below, takes the box in her arms and begins her dangerous journey with Nelly's baby across the Ghetto Wall.
