Fumie, a married woman whose sex life has been dormant for half a year, harbors deep dissatisfaction with her husband Jiro. Jiro suffers from hemorrhoids—whether this is linked to his sexual dysfunction remains unclear—but their marital relationship continues to deteriorate. Burdened with these frustrations, Fumie confides in her acupuncturist, Ohsawa. Hearing her troubles, Ohsawa impulsively pins her down and takes her right then and there. Overwhelmed by his intense lovemaking, Fumie begins seeking fulfillment from other men around her. Her awakened feminine instincts drive her to pursue one new partner after another.
