Nü hei xia Huang Ying

Nearly every English language home video version of this film (NE HEI XIA HUANG YING/DEADLY DREAM WOMAN) uses the title LADY BLACK MASK. Yet, for some reason, if you type that title into the Internet Movie DataBase, it cannot find a match. (This film has no connection to the Jett Li thriller BLACK MASK, or its sequel, by the way, but is still an entertaining martial arts thriller.) When female mercenary Nightingale Wong is knocked unconscious during a fight, she awakens with amnesia in a brothel. Sensing an opportunity, the establishment's madam welcomes the newcomer into her happy little family. Needless to say, they do not live happily ever after, especially when the Nightingale's memories begin to come back to her after crossing paths with old enemies.
