The hidden desires deep within a person's psyche spiral out of control through sudden training. Mitsu Higuchi is a girl who has lived alone with her mother since childhood. One year ago, her mother remarried—but shortly afterward fell ill and passed away. Consumed by guilt over the incident, Mitsu receives warm encouragement from her stepfather, whom she comes to deeply respect and admire. However, suddenly and without warning, he subjects her to intense discipline. Bound tightly with hemp rope, she begins to awaken to new, unfamiliar emotions. A powerful performance capturing the fusion of repressed inner desires and the shocking impact of training.
