Sounds like fantastic grounds for asylum, IMHO, if they wish to apply for it. I know that would mean leaving their friends and family, but it would keep them alive, at least.
How about give the women a choice: They can stay in Pakistan and the film will not be shown, or the can get asylum for themselves and their children, get the hell out of Pakistand and then the film will be released there.
You can't fight ignorance. Don't show the film.
