The “Seven Cutter” is a legend around high schools across the country. His name is Han Su and he remains unbeaten throughout the school system. Whoever tries to fight him not only faces the indignity of losing but is left with Han-Su’s trademark 7cm scar to remind them of their loss. When innocent new kid Han Su (An Jae Mo - Haan, Birdcage Inn) starts at Seong Ji High School, he is instantly mistaken for the “Seven Cutter”. He is blissfully unaware of why the other students are giving him such an icy reception, and so when the toughest boy at Seong Ji challenges Han Su to a fight, he has no choice but defend himself. And when he accidentally wins, things start getting really confusing for Han Su. Also starring comedian Jung June Ha and former Baby VOX member Yoon Eun Hye (Goong) in her big screen debut.
