Louis (Yuriko Yoshitaka), a 19-year-old girl wandering the streets of Shibuya, Tokyo, is full of despair in life. One day, she met a punk youth Ama (Kengo Kora) at a disco. Ama has pierced nails, tattooed and split tongues, and her style is fashionable and avant-garde. With Ama's introduction, Louis is quite interested in snake tongues. They came to the tattoo artist Arata's shop together. The pain of piercing and tattooing made Louis experience unprecedented pleasure, and Arata, who is bisexual and has a sadistic desire, was also fascinated by the petite woman in front of him. Unlike the cold and even somewhat gloomy Arata, Ama looks scary on the outside but gentle on the inside. He loves Louis deeply, and even fights with gangsters for his beloved woman, which foreshadows his tragedy...
