簡介：　　No matter how much he devotes to his sport, veteran boxer Urita remains in the blue corner – the domain of the underdog in the ring. Despite on a permanent losing streak, his meticulous analysis of fights benefits Ogawa, a gifted talent and champion hopeful, and Narasaki, a timid rookie, both gaining strength and confidence under his discipline. Punching his 30 years of boxing experience into the screenplay and the choreography of action sequences, director Yoshida Keisuke uppercuts a realistically crafted drama that underscores the passion, sacrifice and camaraderie in the world of combative sports.
