The film focuses on an evangelical Christian camp of rare devotion. Twelve-year-old Levi, who was "saved" when he was five, is a shy boy except when he is filled with the Holy Spirit. Nine-year-old Rachael is outspoken in her love for the Lord. They are home-schooled by their Christian parents and interact with their peers at church and church events. In the summer they travel to Becky Fischer's "Kids on Fire" summer camp in Devil's Lake, North Dakota, to intensify their devotion to the Lord.
