The Dorothy Day story: A conversation with documentary filmmaker Martin Doblmeier

This week's guest, Martin Doblmeier, is a documentary filmmaker specializing in content touching on faith, religion and spirituality. He joined host Bill Baker for a discussion on his recent PBS film, "Revolution of the Heart: The Dorothy Day Story."

"Revolution of the Heart: The Dorothy Day Story" traces Dorothy Day's journey from a young communist journalist, to a Catholic convert, to the co-founder of The Catholic Worker newspaper and the first "houses of hospitality," which sheltered New York City's homeless during the Great Depression.
