Three sisters, Shinobu, Satsui and Sumire live with their abusive stepfather and mother in a poor area of modern Tokyo. One works as a secretary, the other as a prostitute, and the third as a criminal. The secretary is unhappy with the sexist business world, which limits her opportunities for advancement and makes her a target for her lecherous boss. The prostitute leads an aimless life, drifts between men and often becomes a target for police or jealous wives. The criminal, who lives by disrupting the society which oppresses her two sisters, is the only happy one of the three.
