Tenth graders Oh Dong-seok, Lee Dae-bal and Ryu Ki-seong live in the same neighborhood and go to the same school. They are enjoying their summer vacation. They attend a discussion academy to apply for university and slowly, they start getting interested in women. They open up to porn. They always talk about it and share new porn, getting deeper into the world of it. Everything looks like porn to them. They have wet dreams and spend a period of passion and blood-boiling time.
