大平正

The film centers a compassionate teacher (Setsuko Hara) who teaches at a Tokyo grade school where students curse and gamble. The school has a pond on-premises that she's in charge of and cares for. The pond holds a number of carp, but someone is snatching them. The teacher forms a special bond with a child who lives in abject poverty.

Hideki Yamaga runs a used bookstore in Ginza. He is a man known for his great physical strength, helping the weak and standing up to the strong, and is deeply respected and loved by the women of the city. Nicknamed “The Lone Wolf,” Hideki takes special care of street children. One morning, he rescues Kim Ono, a country girl who was standing there dazed with a single duffel bag, and asks Katsuko, the owner of a dressmaking shop he knows well, to hire her.
