Naniwa erejî
Sumiko Asai (Yoko Umemura) is the owner of the Asai Drug Company. He is unhappily married with a nagging wife, who unashamedly visits the theatre with his male colleagues. Mr Asai tries to get one of his employees, telephone operator Ayako Murai (Isuzu Yamada), to meet him for dinner. She discusses this after work with a male colleague (and apparently boyfriend), Mr Nishimura, revealing that her father is in serious difficulties: unemployed and threatened with arrest after embezzling 300 yen.
After an argument at home she decides to take up Mr Asai's offer and become his mistress. She quits her job and lives alone in a modern apartment block, bored and waiting for Mr Asai. When they attend a Bunraku puppet show, Dr Yoko calls them out. His wife greets them, furious that they are having an affair. However, Mr Fujino, a business acquaintance of Asai intervenes, lying that Ayako was his date, not Asai's.
Ayako accidentally meets Mr Nishimura and explains her geisha-like attire as being due to now working in a beauty salon. She is told that her father is now working at her old company for Mr Asai. Mr Nishimura asks to marry her and she runs off in embarrassment. Due to a misunderstanding, the doctor goes to Mr Asai's house when he is told Asai is ill and the wife guesses that he is with Ayako and tracks him down in his sick-bed with Ayako tending him. Mrs Asai demands that the affair ends and it does, but Ayako has paid her father's debt and keeps her apartment.
Ayako learns that her brother needs 200 yen for his tuition fees and sends the money, acquiring it from her new admirer, Mr Fujino. She leaves Fujino once she has the necessary 200 yen and contacts her old love, Nishimura, confessing everything to him and hoping they can still marry. Mr Fujino comes to her door, demanding she returns the 200 yen, but Ayako responds with disrespect and he leaves, saying there will be trouble.
The police then interview Ayako and Nishimura. Ayako hears Nishimura say that he never wanted to marry her and was dragged into the affair, and he is released. As it is her first offence, she is also released without charge, but into the care of her father. At their home, Hiroshi is there and Ayako joins them and tries to make conversation. Her sister says she can no longer go to school due to the story being in all the papers. Her brother calls her a delinquent and says she should leave. Ayako leaves into the night and stops at a bridge. The doctor passes and she asks if there is a cure for female delinquency. He answers in the negative and walks off.
