Sister Street Fighter 2 Hanging by a Thread - Japanese Martial Arts DVD subtitle

SISTER STREETFIGHTER: HANGING BY A THREAD (1974; aka SISTER STREETFIGHTER 2) is a follow-up to SISTER STREETFIGHTER and has Hong Kong resident and martial artist Koryu Lee (Etsuko Shihomi) coming back to Tokyo to track down a female friend; Birei; who's been kidnapped by diamond smugglers. It's an early '70s Japanese martial arts crime film with abundant nudity; bloodshed; torture; outlandish fashions and a peculiar criminal-dominated alternate universe where there are no cops and the gangsters avoid guns but hire martial artists--the more exotic the better--to do their fighting for them. It's all beautifully photographed on dramatic locations and garish sets. One fight takes place amidst empty racetrack stands and another takes place in a railroad yard and has the heroine battle an opponent atop a moving boxcar. There's even a fight among logs floating in the water at one point. English subtitled.
