From Magnolia pictures. Here's the trailer:

Jesus Camp, directed by Heidi Ewing and Rachel Grady (The Boys of Baraka), follows Levi, Rachael, Tory and a number of other young children to Pastor Becky Fischer's Kids on Fire summer camp in Devil's Lake, North Dakota, where kids as young as 6 years-old are taught to become dedicated Christian soldiers in God's army.

The film follows these children at camp as they hone their prophetic gifts and are schooled in how to take back America for Christ. The film is a first-ever look into an intense training ground that recruits born-again Christian children to become an active part of America's political future.
