This was the first in a series of movies that went under the title of "Onna hissatsu-ken," or "Lethal Fist of the Woman," intended to showcase the talents of Shihomi Etsuko, a female Japanese martial artist trained in Shaolin Kenpo. It is not a Sonny Chiba film, and as other reviewers have pointed out, he only has a small part.
That said, the movie is best enjoyed on its own campy terms. It takes itself perfectly seriously, although it's nothing more than a pastiche of elements swiped from contemporary Hong Kong films-- and pretty much every villain tries his level best to imitate Bruce Lee's deadpan fighting style. In true Japan style, however, the fights are over the top, extremely bloody, and sometimes just ridiculous. In short, it's hilarious. The fights get more and more brutal (and laughable) as the day-glo blood pours. This movie is sure to satisfy those looking for surreal, cheesy fun, but certainly won't appeal to people looking for a high-quality martial arts film. I really enjoy watching the star, since she always manages to appear so sincere in her roles and isn't a bad martial artist. Sadly, her talents were squandered in increasingly formulaic and silly movies.
Please note that I can't vouch for the quality of this release, since I've only seen the Japanese original.
