Japanewse martial arts action. Original title: Yasagure anego den: Sôkatsu rinchi (やさぐれ姐御伝 総括リンチ)
Gambling swordswoman Ochô allies with a gang of prostitutes forced by a Yakuza clan – whose boss has kidnapped the daughter of its previous lord – into smuggling drugs in their vaginas.
As the good lord intended.

I just watched Species in the first time forever and was surprised that Natasha Henstridge didnt do full frontal in it. I always thought she did. Mandela effect?
She had a better nude fight scene in Sex and Fury. Which I think is a prequel to this one. I do like this bit of trivia from it:
“Reiko Ike had to be fully nude for days while filming her sword fight with the group of male samurai. The scene was shot from angles to avoid showing her pubic area on screen, but she said in an interview that all of the actors and crew could see every part of her, including between her legs as she spun around and moved into different positions. She said after awhile it didn’t bother her anymore and just ignored the fact that she was nude.”
The only movie scenes that really beat this are Alice Tseng from Ninja: The Final Duel and Olivia Cheng from Marco Polo. Some of the best naked martial arts ever (well, there are a few other Hong Kong Category III ones).
