The Church of Jesus Christ of Latter-day Saints is one of America's fastest growing religions, and its influence circles the globe. The church has 11 million members today and over half of them live outside the U.S. Yet the birth of Mormonism and its history are one of America's great neglected narratives. This four-hour documentary brings together FRONTLINE and AMERICAN EXPERIENCE in their first co-production to provide a searching portrait of this fascinating but often misunderstood religion. Produced by award-winning filmmaker Helen Whitney ("Faith and Doubt at Ground Zero," "John Paul II: The Millennial Pope"), the film explores the richness, the complexities and the controversies of the Mormons' story as told through interviews with leaders and members of the church, with leading writers and historians and with supporters and critics of the Mormon faith.
