Ryoko Mitake, a nurse at a hospital, gets caught up in a series of unsettling events that occur in the hospital rooms. A leg fetish patient can't resist attacking Ryoko, and a butt fetish patient who overhears her struggling can't help but confront Ryoko after her shift without wearing any underwear. The situation takes a turn when a stench fetish doctor finds out and forcefully teases Ryoko with a vibrator while she's on night duty, making her experience a series of masochistic pleasures. Ryoko forgets her position as a nurse and is drawn into a world of fetish play within the hospital, showcasing her lewd behavior.
