Shizune is a sharp, slender career woman who looks stunning in a suit and glasses. Despite being attractive and successful, her blunt confidence makes coworkers consider her unapproachable, so after workplace stress and a breakup she turns to a dating app. Polite and considerate in person, she reveals the opposite side of herself when pushed: a deeply submissive masochist craving the thrills she cannot show in public. She is dominated, used like a sex toy, and conditioned into total obedience and sex addiction in this intense documentary.
