In mid-1970s, three boys from a southern village become friends while spending time in a boxing camp. Piak (Akara Amarttayakul) is a boxer whose young soul bubbles with fighting spirit. Pao (Thawatchai Penpakdee) is the son of a Chaiya boxing legend. They both hang out with another local boy called Samor (Sonthaya Chitmanee). Amid the backdrop of the peaceful South, the three boys spend time training with the hope of fulfilling their dream of becoming professional boxers.Pao has an old manuscript of Muay-Thai Chaiya left by his father, and the three friends are hugely inspired by the elegant moves and forceful blows depicted in it. But their paths are strewn with obstacles, and their friendship faces an ultimately test when Piak and Pao fall in love with the same woman, a pretty nurse called Sriprai (Parita Kongpech).One day, Pao’s father returns. His name is Tew Chaiya (Samart Payakarun), and he has disappeared after a match-fixing scandal that involved a boxing champion Krangsuk (Prawit Kittichanthira). Upon his return, Tew Chaiya begins to pass on the venerated principle of Muay-Thai Chaiya to his son, as well as to Piak and Samor, making them the last practitioners of this ancient and mysterious art.Soon the three boys are ready to conquer Bangkok boxing rings. In the capital, the debuting prizefighters are forced to learn the hard lessons in the dog-eat-dog world of professional boxing, meanwhile Piak falls for a lovelorn go-go girl named Warn (Sangtong Ket-U-Tong). The battle of the three friends are as brutal and breathtaking in as it is out of the ring.
