A new look at a big question. Inspired by The Calling, a PBS mini-series.
Mark Horvath has been a drug addict, a con artist, a producer for Christian television, and for a time, homeless. Now, he's using social media to raise awareness about homelessness and poverty in America. Armed with a website (invisiblepeople.tv), Twitter account, and a camera, Mark's on a mission to give "a face and a voice to homelessness."
