As I said I saw this in German so I can't be sure how much I understood but I think it goes something like this: a group of white women are sold into slavery by some pirates t some warlord who runs a town. The women are to be prostitutes and sex slaves. The women are secretly trained in various martial arts by a woman who is trying to get rid of the warlord. At some point the women fight back and a huge battle ensues with the half dressed women fighting for their freedom against an army of men dressed as ninjas.
I really liked this movie a great deal even though I saw this in German sans subtitles. I didn't understand anything other than what could be shown, but with action this good it didn't make any difference. This is pure exploitation gold. The movie seems funny (intentionally), it has good acting, beautiful people, great action and the sense to just keep going. Its wonderful fun.
See this movie, even if you have to see it un-dubbed or subtitled, this is a movie that should be sought out by action and exploitation lovers everywhere.
