Booting lives in a small and peaceful village. One day a sacred Buddha statuette called Ong Bak is stolen from the village by an immoral businessman. It soon becomes the task of a voluntary young man, Boonting (Phanom Yeeram), to track down the thief in Bangkok and reclaim the religious treasure. Along the way, Boonting uses his astonishing athleticism and traditional Muay Thai skills to combat his adversaries.

Ong Bak 3 picks up where Ong Bak 2 had left off. Tien is captured and almost beaten to death before he is saved and brought back to the Kana Khone villagers. There he is taught meditation and how to deal with his Karma, but very soon his arch rival returns challenging Tien for a final duel.
