In a military family, an illegitimate son is brutalized by his brothers. A patriarchal, feudalistic household where dissent is forbidden is used to reveal the whole imperialist system that afflicted Japan between 1921 and 1946.

A jobless young couple, Yoshigi and Tsutue, wind up at the outskirts of the Suzaki red-light district in Tokyo. Tsutue talks her way into a job pouring sake for male customers at a small bar run by a sympathetic older woman, while Yoshigi is shunted off into a nearby noodle shop, where he gets a job delivering noodles. Tsutue charms and runs off with one of her clients. Yoshigi, ignoring the attentions of a sweet co-worker, pursues Tsutue.
