Angela Mao faces a firing squad in the opening scene. The rest of the movie is flashback. The plot seems to be - her dad is sick and in debt. He is forced to retire and is replaced by an idiot. The bill collector kills him and rapes his wife. Angela gets revenge. They execute her for his murder.
My warning is to read what I wrote above and save yourself the torture of this movie. I actually wrote a much longer review but I won't post it because it was not worth the effort to write and would not be worth your trouble to read.
The abortion scene drags this movie into the gutter, visually and for rating. The abortion has a song and dance number. Who knew an abortion could result in people dancing and singing?
Perhaps the best way to look at this movie is as a bad porno. The set up of this movie is really typical of the terrible porn that came out of the early 1970s. The movie makers were trying to avoid the censors, even trying to avoid being arrested for making sex scenes. The result was total lack of quality in every aspect. No sense trying to understand it at this point. Any way you look at it, I consider this movie a steaming turd.
"So what about the fights?" is the standard question by fans of martial arts movies from this era. They are nothing special and often lost in the darkness of the set or the filming process.
I rate this movie low and my recommendation is to forget about it.
