Martial arts expert Ho Chiang journeys to America's Wild West on a life-or-death mission: he must retrieve his late uncle Wang's missing fortune and return it to a powerful Warlord (the original owner of the fortune), or his family will be executed. Ho frees the thief who unintentionally killed his uncle after blowing Wang's safe, Dakota, as he is the only man who knows Wang's final resting place. Upon recovering the body, the pair discovers clues pointing to an apparent buried treasure. Notes on the dead man's body promise that the location of the treasure will be illuminated by a Treasure map, divided for security into four segments, each one tattooed as a message on the buttocks of all of Wang's four mistresses. Armed with photographs of the women, Ho and Dakota form an uneasy alliance and set out in search of the map tattoos and the promised riches, only to be closely followed by a bloodthirsty Preacher, who wants to divide the fortune between himself, a strong Native Americans in the United States ringfighter and a gang of criminals.
