It’s an kung-fu-esque flick from the early 70’s called “Sex and Fury”.
It takes place in Japan with a female protagonist who is a bit of grifter and wanders the shadows of the Japanese underworld. She also kills lots and lots of people naked. That’s right. For five minutes and all in slow-motion, Yuki cuts her way through an army of Yakuza while in her birthday suit. “Jiggly” just doesn’t describe how that scene looked. Though the director made certain her naughty bits weren’t seen. Pure fun.
