A grisly murder occurs in Maruyama-cho, Shibuya, Tokyo – a love hotel district – where a woman is found dead in a derelict apartment. Whilst the police investigate, the story interweaves with that of Izumi, the wife of a famous romantic novelist whose life seems just a daily repetition without romance. One day, to break away from the loveless monotony, she decides to follow her desires and accepts a job as a nude model enacting sex in front of the camera. Soon she meets with a mentor and starts selling her body to strangers, whilst at home she hides behind the facade that she is still the wife she is supposed to be.
