A gifted athlete with natural movement abilities, Wheesung abandoned sports after a high school injury and now scrapes by with part-time jobs. By chance, he attends an amateur MMA fight featuring his friend Junghwan. Experiencing the raw power of the Octagon for the first time, he feels an electrifying thrill he can’t ignore. At 22, Lee Hwi-sung had been fleeing from his past and his own potential. The instant he steps into that fighting cage, an astonishing and unexpected journey of triumph begins.
