Only the Shaw Brothers Studio could conceive and produce such a spectacular clash of esoteric weapons. Fans of the internationally popular "Flying Guillotine" films will appreciate the continuous kung-fu confrontations with some of the most intriguing and exciting martial arts machinery ever seen on screen. The studio’s first international action star, Lo Lieh (who burst upon the scene before even Bruce Lee in King Boxer) leads the charge as holder of the title tool - an ultra-cool flying boomerang with blades. He must take on the terrible Iron Ball Chain, Golden Net, and other deadly devices to gain control of a special elixir which will cure an all-too-treacherous royal official. Tang Chia and Yuen Cheung-yan, the underrated giants of kung-fu choreography, stage some of the best sword on shield action ever in this fun and unusual fight-fest. There are double crosses and ambushes galore before the culminating clash of sizzling steel that has to be seen to be believed.
