Trapped and completely immobilized in a cast, the young girl "Asuka" regains consciousness only to find herself face to face with "Sato," the physician who attacked her and left her incapacitated. Forced to rely entirely on her captor for food, hygiene, and bodily functions, her days are ruled by fear, shame, and humiliation. One day, she realizes her right hand can move and attempts to escape—but is quickly caught by the man, who mocks, degrades, and violently assaults her. As hope fades and despair takes over, her mind slowly collapses.
