I stumbled on this today and I have to say I was really impressed. It’s a short film which starts at Buakaw’s surprise loss to Andy Souwer in the 2005 K-1 World Max tournament. After this, it quickly goes back in time to where he is a young boy, discovering Muay Thai for the first time. As with most life stories there are a few ups and downs but it shows you him getting his revenge on Souwer in the 2006 K-1 World Max tournament.
A few of the translations are dodgy but you get the idea of what’s going on…enjoy.
