Four tragic widows sink deeper into the pain and ecstasy of hemp-rope bondage. After Akari suddenly loses her husband, Kito gently takes the hand of a woman with nowhere else to go. Aya faces selling her factory to repay debts after her husband's fatal accident, but seeing her kneel awakens Sakashita's evil desire. Kurumi marries an heir for status and tries to win over her father-in-law to preserve it. Sayuki tells her father-in-law she wants a job instead of living on his income forever; he agrees, then pushes her down and assaults her that night.
