Director Chun-Ku Lu (Holy Flame of the Martial World) is here to tell us the story of Yun Fei Yang (Norman Chui), an orphan who is given the worst tasks at Wudang, a martial arts school. Every privileged student abuses him, but he remains there, studying and working on his kung fu when he isn't being treated like trash. There's a real problem, however, as the rival Wu Di school and their best fighter, Kung Suen Wang (Meng Lo), is coming back to duel the school's master swordsman Qing Song (Jung Wang) after having already defeated him twice.

Yun Fei Yang also is in love with the daughter - Fang Er (Yeung Jing-Jing) - of the leader of the school, Chief Dugu (Alex Man Chi-Leung), who has left for two years. As Dugu rests as a tavern, he's attacked by four killers - Wind (Yuen Tak), Thunder (Wong Lik), Rain (Yuen Qiu) and Lightning (Kwan Fung), in case you ever wondered if John Carpenter watched these movies - and is saved by Fu Yu Shu. Yet after he's attacked a second time, Yun Fei Yang is blamed and the school starts to tear itself to pieces A new master shows up, Fu Yu Xue (Tony Liu), and he soon steals away the school.

Yun Fei Yang starts to train with a stranger - Shen Man Jiun (Chan Si-Gaai) - and begins to master the signature style of the school, the Silkworm, all while running for the law, who thinks that he is a murderer. Yet despite the odds being against this "b******," the only way the true Wudang style will live on is through him.

Don't think that this movie is rooted in our world. After all, Yun Fei Yang soon learns how to spin himself into a cocoon and emerge as a silver armored superhero who can shoot webs and emit blasts of energy. By the end, the final battle takes place inside his cocoon and it ends with the bad guy turned into a skeleton.

Based on a TV series, Reincarnated or The Transformation of the Heavenly Silkworm, this would be followed by a sequel, Return of the B****** Swordsman.

The Wu Tang clan has the secret of the silkworm kung fu technique, but its Chief has always been defeated by the Chief of the Invincible clan, with whom he fights every 10 years. One day a mysterious stranger arrives at the Wu Tang compound and rapidly rises up the kung fu ladder, while at the same time lowly servant Yun, of unknown parentage, is secretly learning kung fu from a masked master. When the clans inevitably clash, who will survive? Will the secret of the silkworm technique finally be revealed? And maybe some of these people will even find True Love as well…. It's very hard to describe the kung fu movies made by the Shaw Brothers, basically because the plots are so incredibly loopy; this particular example all but jettisons the idea of plot altogether, the better to throw in more and more kung fu contests! One thing I love about this zaniness is that there are always female fighters as well as male, and they are all equal in skill; but regardless of gender, it's the action scenes for which one watches these films, and "Bastard Swordsman" ranks up there with the best of them!
