Every morning, Yukie sees her husband off before spending her days busy with housework and laundry. Her afternoons are spent idly in front of the television—a completely ordinary housewife's life. But her routine is disrupted by her neighbor, Mr. Asano. One afternoon, shortly after sending her husband off and finishing her chores, Asano visits her home. He hands her a magazine, revealing a humiliating secret from her past—one she's kept hidden from her husband. From that moment on, during the hours when her husband is away, Yukie's days become filled with torment as Asano exploits her vulnerability. Burdened with guilt toward her husband, she gradually begins to awaken to her own masochistic desires.
