Without money and a place to sleep, Kuniko offers her services to a man who turns out to be a detective, and she is sent back to the reformatory.
She decides to be frank about her past to her female co-workers, only to learn that they offer sexual services to other men themselves.
Kuniko returns to the reformatory, whose director Mrs. Nogami confronts the factory owner and the girls involved in the incident.
Mrs. Shima hands Kuniko a letter by Tsukasa's mother who declares that she won't allow her son to marry a woman with her past.
Girls of the Night was shown as part of a retrospective on Kinuyo Tanaka at the Japan Society, New York, in March 1993.
