Over more than a decade, the daughter of a Kyoto Imperial University professor comes of age as she witnesses her father fired for opposing the rise of fascism in Japan and becomes involved with two of his students.
Two young girls, Nobiko and Tomiko, go to the same school. The less fortunate girl Nobiko is one of the top students, while the rich girl Tomiko is not. At one time Tomiko's father was quite fond of Nobuko's mother.
