A troubled ex-prostitute turned barkeep is enchanted by the love of a younger man named Kenichi. After trusting a violent junkie to help with her young lover’s singing career, she is sent to prison for murder. Now known only as Prisoner 101, she spends her days in the dirty prison system full of violent guards and sexually-aggressive inmates.

After her husband's suicide, young and beautiful Mitsuko Fuji feels alone and helpless -- until one of her husband's major creditors, Mr. Kito, offers a sympathetic ear and a cancellation of all debts. However, Mitsuko soon learns that Kito's intentions are anything but pure, as she's forced to become his personal concubine. Her only, improbable hope for redemption lies with her one true admirer: Kito's very own son.
