What happens to women involved in human trafficking rings?

Today we examine how international sex trafficking networks operate, how women are coerced into them, and how those women fare once freed from sexual enslavement. Also, a nonprofit group in Arizona tries to increase cross-border understanding through tourism. And, last night the Oscar for best documentary short went to "Period. End Of Sentence," a film about the practice in some cultures of banishing women who are menstruating. We meet a Nepali woman who is working to end the practice in her country.
