A wealthy kung fu expert who was turned bitter and evil by his wife's slaying and the amputation of his son's hands, bullies a town through terror and force. They find pleasure and satisfaction by disabling those who stumble into their way. Four of these victims--a hawker who is blinded, a blacksmith made mute and deaf, a drifter who loses his legs, and a fighter who loses his sanity--band together to use their disabilities to the best of their advantage. The four are tested time and time again and demonstrate their strengths and abilities.—Chris Castellano
