Brand new factory sealed dvd has optional English soundtrack.

The story is set in 1890s Siam. Siang is a young Muay Thai warrior and rocketry expert who steals back water buffalo taken from poor Thailand farmers by unscupulous cattle raiders. He is searching for a man with a tattoo that killed his parents.

A local nobleman, Lord Waeng, wants to create a market for his steam tractors, so he hires a hulking convict, "The Thief", to kill all the cattle traders and round up all the water buffalo for slaughter, depriving farmers of the working animals they need to cultivite rice. Lord Waeng's men are eventually pitted against Nai Hoi Sing, a cattle trader with supernatural martial arts powers and a tattoo on his chest. The tattoo gets Siang's attention, and while the Thief is trying to steal Sing's cattle herd, Siang briefly confronts Sing but is repelled.

Lord Waeng consults the Black Wizard, who was once cursed by Sing so that he cannot withstand  sunlight, to find a way to defeat Sing. The Black Wizard says the only way to reverse his spells is to use the menstrual blood of a virgin -- the Black Wizard's daughter, E'Sao.
