Khon Fai Bin) is a 2006 Thai martial arts Western film directed by Chalerm Wongpim and starring Dan Chupong (from Born to Fight).

[1] Siang is a young Muay Thai warrior and rocketry expert, raised in a Buddhist temple, who steals back water buffalo taken from poor Isan farmers by unscrupulous cattle raiders.

Lord Waeng's men are eventually pitted against Nai Hoi Singh, a cattle trader with supernatural powers and a tattoo on his chest.

In Waeng's palace, Dam also reveals that E'Sao is not his daughter, but a baby he kidnapped, and intends to rape her so Singh remains magically disabled for good.

The weakened Singh dies in a magical duel against Dam, but Siang defeats the black wizard, who is obstructed by Waeng's lingering mind.
