洲崎パラダイス　赤信号

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.
