Starring Rachel Weisz, and set in 1999 post-war Bosnia and about the sex trade. The fact that sex trafficking is still a major problem in the world is horrifying and this movie will piss you off. Look I know the characters are composites and fictionalized but the overall story is a true one....Tough movie but very good.. Weisz is very good.. Not sure the budget but it only made a tad over a million..
