Li Koryu (Etsuko Shihomi) returns to fight crime in Japan in the second in the Sister Street Fighter series, Hanging by a Thread (女必殺拳 危機一, Onna hissatsu ken: Kiki ippatsu). The first film apparently tested so well so that studio execs ordered a second one right away to fill a big New Year slot. That might in one sense explain why the film is pretty much the same in terms of narrative, yet this one does go a little further while swapping the drugs subplot for diamonds.
Koryu comes to the aid of a man being attacked by thugs in a Hong Kong marketplace and is somehow completely unfazed when he plucks out his false eye with instructions to give it to Professor Enmei (Hideaki Nagai) who is also known to Koryu because he’s the father of her old school friend, Birei (Hisako Tanaka). Unfortunately, the false eye contains microfilm that suggests Birei has been kidnapped by vicious Japanese gangsters. The professor therefore sends her to Tokyo on a rescue mission and we discover that she also has an older sister, Byakuren (Kanya Tsukasa), who was never mentioned in the earlier film, who is living in Japan having chased her dream of becoming a jewellery designer.
This time around, it’s diamonds not drugs, but the gangsters still haven’t cracked this smuggling business and have come up with the very weird idea of hiding them in the bum cheeks of attractive young women. Meanwhile, they also force the women into sex work. Osone’s (Hideo Murota) female business partner Mayumi, played by Madam Joy, a drag queen who starred in several Toei films in the mid-70s, films them from a distant window to get material for blackmail. Nevertheless, she only cares about the diamonds, unlike the boss and several of the gang which once again includes a rival martial arts outfit who have in it for the Shorinji temple.
Shinichi Chiba does not appear in the film, but Koryu does gain a kind of sidekick in the form of Tsubaki (Yasuaki Kurata), a sleazy-looking guy whose intentions are permanently unclear. The film goes a little bit further with its awkward orientalism opening in a Hong Kong marketplace with some offensively stereotypical music and a bunch of fire crackers, even if once again in trends in the opposite direction from most films of the time in that the crooks are all Japanese and it’s a half-Chinese woman who’s coming to sort them all out. The gangsters have apparently been trafficking the women abroad for sex work, then bringing them back with the diamonds in their bums which seems like a plan with a lot of potential problems even if they hadn’t made the huge mistake of kidnapping a friend of Koryu and then later her sister.
But then again, Koryu’s cases seem to be fairly isolated. Once she takes out these bad guys, that’s it. There’s no wider conspiracy save a general sense that the world itself is corrupt and indifferent to human suffering. Osone has a strange love of taking people’s eyes, which might be a way to stop them seeing who he really is. He has, after all, already taken the stars from Byakuren’s along with her dreams of a new life in Japan finally becoming the jewellery designer she always dreamed of being. Despite her determination to save her sister, Byakuren soon realises that Osone is most definitely not a man of his word. His curiously old-fashioned outfits and demeanour suggest he’s seeking a place with the elites of an earlier time while indulging in some fairly odd behaviour.
Once again, Koryu squares off against his equally weird henchmen who start attacking her the moment she lands in Japan, and eventually ends up stabbing someone with the severed arm of another enemy still holding his knife. Still, the tone is generally cheerful and upbeat despite the strangeness of the tale and series of losses Koryu experiences including a challenge to her pride when she’s bested by one of the martial arts goons. In this continually uncertain and increasingly surreal world, Koryu’s fists, it seems, are one of the few things that can absolutely be relied upon along with evil smugglers and their bizarre new plans for circumventing the law of the land out of nothing other than lust and greed.
