It's one of the saddest truths of our time - the fact that to this day, slavery and human trafficking exist in our world. You can see the results if you look carefully almost anywhere. But where, and how, do the victims get caught up in this evil system in the first place?

That's the question that Greta van Susteren has been working on lately. The host of On the Record is just back from a trip to some of the farthest reaches of the world in an effort to find out more. In this very special edition of Greta Talk, she is on the road. Literally. Sitting next to her in a rugged vehicle is Barry Jessen, the director of the Samaritan's Purse Anti-Trafficking Program in Cambodia. You'll want to listen closely, as he takes her (and us) to where some of the poorest of the poor get snagged. And we'll hear what kinds of efforts are underway to change things!
