Yeong Gun believes she is a cyborg. Instead of eating food, she charges herself using her transistor radio. While wearing her grandmother's dentures, she walks around the mental institution that she stays at, feeling a greater connection to the electrical appliances than to any human. Surrounding her are a group of similarly interesting and antisocial characters. One of them is Il Sun, who tries to convince others that he can steal their personalities and attitudes. Yeong Gun is attracted to his awkward quirkiness and he admires her for her beautiful big front teeth. She asks him at a group counselling session to steal her sympathy. His attention is caught, and he finds his interest in her grow as her body weakens.
