This is a surprisingly important film, representing the break between Hong Kong studios production of Martial Arts movies and the contemporary action/adventure yarns that would dominate the industry in the 1980's. Within THAT subgenre , the "girls-n-guns" motif became one of the most reliable (some would say cliched) breadwinners for the HK industry. This, produced in 1976, was one of the first, and for my money one of the best! There's a plot in there somewhere about a diamond smuggling operation, but this one works if you check your logic circits at the door and enjoy the spectacle of some great looking athletic young women doing battle with the usual assortment of one-dimentional sadistic triad bosses. Kind of similar to Charlie's Angels from US television, except their "Bosley" is the lovely Evlynn Kraft of 'Mighty Peking Man' fame...it's a good thing for everyone that no one tried to fit David Doyle into some of Kraft's hot pants and go go boots outfits! If you can find this one....check it out!
