Once Upon a Time in High School
“Spirit of jeet kune do.”
Nobody at Jungmoon High School can say why a model student would ask to be sent there, when the place is known for its beatings and its gangs. Hyeon-su (Kwon Sang-woo) arrives in 1978 and meets Woo-shik (Lee Jung-jin), while Eun-ju (Han Ga-in) stays at the edge of both their lives. Yoo Ha shoots the school as a place of strict teachers and Hyeon-su in the middle of it, a newcomer in a high school in Seoul.
