Jae Seong is a small, unassuming teenager with a troubled history. When he's approached to join a Judo club at school, the power and authority he saw violence could give him tantalized him. After being attacked, he uses the moves he learned against the attacker- only to cause a series of tragic events following the rebuttal. Trauma, violence, and a need for compassion and understanding intertwine as Jae must confront the worst parts of himself before he becomes the very thing he despises.
