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.
