Professor Yun teaches philosophy at a university. He is guided by his own virtuous beliefs, though he was kicked out of seminary school as a student himself for having sex. He is married to a cellist who is highly religious. After Professor Yun is propositioned to have sex to pass a student, he later has a stroke in class and becomes paralyzed. Sook-Hee is a caregiver who goes by her own rules. She is highly sought after because she has "cured" all of her patients. Sook-Hee's next client is Professor Yun. She treats her patient like her child as well as giving him sexual excitement. Maternal instinct and sexuality are intermixed in this daring debut film of a late-blooming director.
