Remake of Kiss Of Death (HK, 1973) with more than a casual nod to I Spit On Your Grave(US, 1978) http://akas.imdb.com/Details?0077713
Ying is horribly gang-raped by five lowlives, leaving her with VD, and she plans revenge, encouraged by her blind sister, but initially discouraged by family friend wheelchair-bound Hung. She starts regardless, and those around her are gradually drawn in. These include a journalist who would be her boyfriend and Susan, who works at the same bar.
Not everything goes to plan. For instance, Ying fails to kill one of the toughs after successfully burning his face with acid.
Only one character is left standing at the end, and all who die, die horribly.
