Angela Markado (1980)

Angela Delmar (Hilda Koronel) works as a waitress in one of Manila's seedier bars, where she meets five bar patrons who turn out to be a gang that specializes in drugging and raping girls and selling them into prostitution. Angela is the only one tending to her mother, a laundrywoman who stopped working due to tuberculosis. One night, she gets kidnapped, raped, and kept for five days by the five men. The men tattoo their names on her back and sell her to a brothel. She escapes and is taken in by a kind hostess (Celia Rodriguez)., but when she gets home she discovers that her mother has died and her best friend was raped by the same odious quintet and later committed suicide. From then on, Angela makes her life's mission to stalk and kill those five men, using wigs and costumes and carrying a handy switchblade.
