20-year-old Jeong-hee doesn't go to college and works part-time. She goes to meet Min-young, her old high school roommate, for the first time in a while and wants to play with her as before. However, Min-young, a college student, is busy sending correction emails for her credits and feels uncomfortable by Jeong-hee's visit.

Lee Ji-sang's Yellow Flower dramatizes the erogenous encounters of a group of Asian men and women, who explore the limits of their own sexuality by participating in deviant, perverse, and bizarre coital acts with one another. Like Nagisa Oshima's In the Realm of the Senses and Ryu Murakami's Tokyo Decadence, Yellow Flower helped to obliterate the censorship of sexual content in motion pictures, throughout Asia.
