We've been trying to remember what movie this is from... I think it's a martial arts type flick, but I don't really remember.
Starts out with a couple hookers going to some person's house/mansion. One goes upstairs for something and while she's up there everyone downstairs is killed (including her friend). Somehow she gets away and our hero finds her and helps keep her safe from the villains since she could identify someone.
Anyone remember what movie this was? I think it was fairly recent... At least since 2000.
