Duke and Yan, two long time rivals, are competing in the world’s most dangerous underground fighting tournament, where powerful crimelords can gamble and influence who they fight, the terrain they fight on and what weapons will be used. In this high-stakes bloodsport where one wrong move can mean certain death, they must decide whether to play by the rules or to cast their honor aside and team up against the dark syndicate running the tournament and bring the entire system down.

　　SomTum是泰国东北部传统菜式之一，也是最受外国朋友欢迎的泰国菜之一，以木瓜丝为主要用料，配以辣椒、柠檬汁、鱼露、花生、虾米凉拌而成，因此中文译名为“凉拌木瓜丝”，这也是我最喜欢的泰国菜之一。
　　影片讲述一个大块头却又胆小的老外一旦吃了SomTum之后就变成变身红色“大怪物”的故事，活脱脱一个绿巨人浩克和大力水手的综合体，这部电影针对的群体很明显并不是泰国本土人士，而是来自西方金发碧眼的游客们，该片融合泰拳、自由搏击与逗趣搞笑於一身，十足的成龙电影架势，不知道会不会有香港或台湾片商对这部片子有兴趣呢？
