Du Tiandao (Chen Guantai), a rural bully, became more violent because his son du Chang (Lu Feng) was chopped off by three tigers in the south of the sky. If the villagers made him feel dissatisfied, they would immediately hurt others. Chen Shun (Guo Chu), Hu Agui (Sun Jian) and Wei Datie (Luo Mang) all inadvertently offended du Tiandao because of trivial matters that were not mentioned, and they successively dug up their blind eyes, cut off their legs, and beat them dumb and deaf. Wang Yi (Jiang Sheng), who is determined to vent his anger for them, was hit hard by du Tiandao and became a crazy person. Four disabled people sneaked into the mountains to find Master Wang Yi and begged him to teach him kung fu. A life-and-death battle took place between four people determined to take revenge and two vicious masters.
