The Lady Avenger (1981) aka Feng huang nu sha xing – Yang Chia-Yun.

A pretty model is sexually assaulted following a dispute on a shoot, and during the following, absolutely biased trial, the wealthy, privileged abuser is corruptly pronounced innocent of any wrong doing, and the aggrieved, dogged crime reporter (Lu Hsiao-Fen) later suffers a similar fate, but eschews the elite-run system, ruthlessly seeking out her own justice in a heroically brutal fashion. While the often sordid rape/revenge milieu has inspired a number of unwatchable dirges, The Lady Avenger remains one of the more exhilaratingly exploitative, grittily violent, and gruesomely executed examples of unleavened female wrath. Unlike the mostly turgid 'I Spit on your Grave', The Lady Avenger is kinetic, compellingly acted, and remarkably well-made, with many rewardingly inventive executions, and providing one of the most stunning man slayers in Cat III history!

The dramatic/expository elements are credible, lending additional gravitas to the carnage, that our sympathetic heroine righteously unleashes! While it is upsetting witnessing the brutal mistreatment of such an intelligent, charismatic, and exquisitely beautiful young woman, I don't believe director Yang's visceral Mise-en-scene was in any way gratuitous. Not long after her terrible ordeal, our bruised phoenix, while cruelly bloodied, remains resolutely unbowed, arising nobly from her despair, vengefully taking flight as a truly indomitable angel of death! It is not altogether frequent that a wholly unfamiliar exploitation title explodes so vividly on my radar, memorably providing such exceptionally WTFuckable content, The Lady Avenger is ripe for rediscovery!
