A middle-aged man falls in love with an angel in a white coat who gives him smiles and comfort during his frustrating hospital stay. He lost his job and is single, and no one comes to visit him. His only joy is interacting with his girlfriend. However, when he sees her flirting with a colleague's boyfriend and asks him with annoyance, "Is that patient gross?", his jealousy and sexual desire explode. He stages a medical error, threatens her, and calls her on the nurse call all day and night, forcing her to satisfy his sexual needs... and her sensitive body becomes a prisoner of his insatiable penis.
