A seemingly noble man is driven mad when his family isbutchered his son has his armed chopped off. He gets his son iron arms, and becomes a ruthless thug. Years later, he cripples the wrong four guys, as they all team up, learn special kung fu and decide to end the man's reign of terror. Possibly my favorite of all the Venom films. Spectacular fights, and the scene of the four crippled heroes limping and carting out of town is pathetically humourous. The crippled avengers are: the deaf and dumb man (Lo Meng), the blind man (Kuo Chui), the idiot (Chiang Sheng--aka "Cutie Pie"), and the legless man (Sun Chien). Lu Feng plays the armless man, and Chen Kuan Tai joins the venoms as the ruthless father.
