Mitsu's husband died in the war, and she was left alone with four children and works as a day laborer. The eldest daughter Haruko, who is already nineteen years old, works in a clothing store, the second daughter Natsuko works in a restaurant, a schoolboy Akio is studying carpentry, and even the youngest Fuyuko helps her mother by working as a nanny in a neighboring house. Nearby lives a widowed electrician Tokuji Yamada with two boys - Norio and Tatsuo. He has a widowed daughter, Sakiko, who, along with a small child, ran away from home, as she is going through hard times.
