One day, a man falls head over heels for a woman named Rino when he sees her on the street. Obsessed, he tracks down her address and begins stalking her, secretly installing hidden cameras in her room to closely observe her daily life, using the footage as material for his masturbation. Unable to approach her directly, his twisted psyche spirals out of control. He hires another man to seduce Rino, then remotely orchestrates her kidnapping and confinement, subjecting her to brutal training. As a result, Rino is forcibly thrust into a life she should have never had to face—walking a path of utter despair.
