Cannot really explain relationships or roles using the typical "mains" and "support". The cast is not properly accredited in the above synopsis. The entire cast, most of which are not even listed above, really shine. Every character presented, is credible and engenders sympathy. The roles of Phat and Wirat generate the appropriate hate for gangsters. The dramatizations are in the same class you expect in kdrama. Thai boxing is a national ceremony of pride and history. My favorite fighter is Yanin Vismitananda. Tony Jaa is a munster of a martial artist with Thai Boxing. In interviews on video and in either Karate Magazine and/or Taekwondo Life, they expressed how Thai Boxing influences the Thai people and culture. This show makes this painfully obvious. In a way I understand easily. Exposure to the miserable life of the young boxers made me want to cuss. Facts provided thru the show really highlight how destructive Thai boxing world can be on people just trying to survive. Getting facts and the dramatizations that display some of these. This show had a huge impact on me. I highly recommend this show for viewing.
