Chik loh go yeung (1992)

The story of a young flirty feral woman named Kitty who is trained by a martial arts specialist to become a professional assassin. She's subsequently recruited by the real killer, a hit woman who targets rapists at large and practices on drooling sex-mad psychos chained up in the attic. When they finally head out for the real thing, they take out victims in a display of midair somersaults, cracking whips, flying ropes, and flashing guns. This kind of foreplay attracts the lustful attentions of rival assassin Carrie Ng, a lesbian killer ready to abandon her purring sex kitten for the savage Chingmy.
