ere Chang Siu Tai (Alexander Fu Sheng) is the son of Master Chang (played by Ku Feng), a renowned chiropractor/bone-setter operating a clinic in a poor neighborhood in an unidentified city in early 20th century China. Siu Tai works for his father and studies bone-setting and kung fu under him, but gets into lots of trouble, especially after white foreigners and their westernized Chinese enablers descend on the town in hopes of acquiring a valuable statue of the Goddess of Mercy on display at a local Buddhist temple.
