血滴子第一代傳人封神無忌,甘為清庭鷹犬,與其師姪左龍、左虎狼狽為奸,無惡不作,專門暗殺明末忠良志士,獨臂拳王俞天龍,不甘清庭暴政,設正德武館授徒,暗中聯絡有志反清復明志士共圖大計,左龍、左虎二人先後被除,人心大快。封神無忌接鴿子傳書,知師姪被殺,大怒,誓言找獨臂拳王報仇……The one-armed boxer is stalked by a vengeful flying guillotine expert, after his disciples were killed in the first 'One-Armed Boxer' film. But as the flying guillotine master is blind, he starts his quest by becoming a serial killer of one-armed men. Meanwhile, the one-armed boxer is running a martial arts school, where he teaches his pupils to control their breath so they can run up walls and along ceilings. And there's an Indian fakir whose arms can extend until they're ten feet long. As you may have gathered, a rational plot summary is pretty pointless - but rest assured there are epic martial arts battles and ludicrously inspired moments galore.
