Married to Takumi for eight years, Ryu lives an ordinary life as a housewife. One day, her routine is shattered when she's suddenly harassed by her husband's younger brother, Goro. Unlike the reserved Takumi, Goro is a womanizing drifter who quickly sets his sights on Ryu. Seizing on a secret she desperately wants to hide, he exploits her vulnerability to force himself upon her. He ties her hands behind her back with a necktie and brutally shaves the hair from her most sensitive areas. "Now you can't have sex with my brother ever again!" he sneers, taunting her with cruel words. This violation marks the beginning of a terrifying new threat to their once-peaceful marriage.
