With little more than a white robe, a blanket and a Bible, Carl James Joseph -- who prefers the moniker "What's His Name" -- set out on a spiritual journey through 47 states and 13 countries to live simply and share the word of God. For three years, filmmaker Sean Tracey follows this humble and homeless preacher, capturing the reactions from both skeptics and believers and offering insights from those whose lives he's touched.
