A martial arts master, Tseng Tien-Tu, is employed by master criminal Lung Tung Chien to transport a valuable jade horse. When the horse inexplicably goes missing, Chien demands Tseng\'s life savings as recompense, driving the uncomprehending Tseng insane. Two conniving con men, Li and Lung, try to convince Tseng that he was double-crossed by Chien, in an attempt to lead them to Chien\'s stockpile of swindled fortunes.
