As a high school student, Jung Woo (Lee Dae Hwi) isn’t exactly at the top of his class's social hierarchy. In fact, as one who is bullied daily, Jung Woo could easily be considered one of the lowest, most unlucky students in his entire school. Struggling every day just to get by, Jung Woo does everything he can to hang on long enough to graduate. But when Jae Seong (Kim Do Yon) and his cronies decide to hold a fighting tournament among the school’s weakest students, Jung Woo finds himself caught up in the school’s biggest, most talked-about event of the year. Determined not to lose, Jung Woo heads to the gym to train, but it isn’t until he meets the school’s new transfer student, Min Ah (Chae Won Bin), that he finds the inspiration he needs to truly fight back.
