A new documentary is shining a light on one of the darkest corners of America — sex-trafficking of children. It's a topic that hits close to home, after a Lowell man was just convicted of drugging a 13-year-old girl, raping her and forcing her into prostitution. Two weeks before that, five others were arrested in connection with trafficking women at brothels around Boston.

"I Am Jane Doe" takes a broader look at the problem of child sex-trafficking, portraying a labyrinth of horror after gut-wrenching horror brought to us the likes of online classified site Backpage.com, which marketed children as "escorts." The film follows epic courtroom battles, congressional hearings and some of the remarkable young women, along with their mothers, who've survived it all. It's the latest work from former lawyer, Olympic rower and current award-winning filmmaker Mary Mazzio, who joined Jim to talk about it.
