Briefly
Brothers Kurt and Eric Sloan go to Thailand, the birthplace of kickboxing, to prove to local fighters the superiority of the American school over the Thai. Eric, the American kickboxing champion, meets Tong Po, the champion of Thailand. Tong Po turns out to be a real beast. He deliberately cripples the already exhausted Eric Sloane, dooming him to disability. Kurt enters training with Thai wrestling master Zen to defeat Tong Po and avenge his paralyzed brother.
