A young factory worker struggles to figure out what she wants to do with her life.

Mototsugu is the younger son of Akira Sakawa, a director of an advertising agency whose mother, Nobuko, is ill with cancer of the liver. His elder brother, Ichiro, works at the Bank of Japan whose wife, Masuko, is from a very high-class family. Mototsugu becomes disgusted with such strait-laced living and leaves home to marry Yoshiko, a blind masseuse, and they live in a small apartment near a pinball parlor where he works.

An ambitious young woman uses her sex appeal to solve financial problems in her family, including a brother in debt to the yakuza, and a father who stole money from his firm to repay his son's debt.
