One night, Tokyo restaurant owners Kichizo and his wife Miyo pursue a drunken writer, Otani, to his home after he walks out on his bill. The next morning Otani's wife Sachi goes to the restaurant, the "Tsubakiya", to stop them from making a police report. She promises to repay them by working at the restaurant. And she proves to be very good at it. The customers really like her and give her generous tips. Meanwhile, her husband wanders from one bar to the next, falling deeper into debt and generally acting badly. He is a successful novelist, but almost none of the money made from his books reaches his bank account. In the end, it becomes a question of whether or not the cheerful Sachi and her recklessa and depressed husband will continue to remain together.
