Suenaga finds his life on the verge of collapsing as violence consumes those around him. However, he finds a worthy opponent in Omura, an up-and-coming wunderkind who is trying to escape his violent past. The men's fight for redemption culminates in a climatic match brimming with raw, testosterone-fueled emotions. Upholding the Rocky Balboa spirit of learning to get hit and keep moving forward, Underdog is a tough, uncompromising epic that deserves a spot in the pantheon of great boxing films.
