Escape from Brothel(1992)

Synopsis

Hung and Ann are down-on-their luck prostitutes trapped in Hong Kong. Pauline's boyfriend, Sam, back in China, who is under the impression that she is away working at a factory, is double-crossed by Billy Chow, and while looking to escape, flees for Hong Kong and winds up at the Brothel where Pauline is employed. He is crushed when he finds out the truth, but by this point, everyone involved on all sides is too deeply involved to turn back.
