What movie is this?

This is what I remember about it: a russian or maybe romanian woman is coming to usa, thinking she's coming to work, but soon realizes that she's been trafficked. There's also other women and the woman protects a young girl and gets raped. In the end of the movie she escapes, calls her mother and finds out her son has been taken, into trafficking apparently, and the woman throws herself off of a cliff. I've searched and googled and scrolled through IMDB but for some reason can't find it. It's a 21st century movie. Please, help me so I can stop obsessing! Thanks!
