In rural Pennsylvania, the World Peace and Unification Sanctuary teaches that God's kingdom on Earth requires an armed congregation, and its members show up to services carrying AR-15 rifles. The film follows the church founded by Hyung Jin "Sean" Moon, son of Unification Church leader Sun Myung Moon, as it fuses his father's teachings with a doctrine that treats the AR-15 as a modern "rod of iron," the weapon it believes will help usher in a righteous kingdom. Cameras sit in on sermons, gun blessing ceremonies, and interviews with congregants who talk plainly about stockpiling weapons and preparing for societal collapse. The film lets Moon and his followers explain their theology in their own words rather than narrating a verdict over them, while also showing the discomfort of neighbors and former members who watched the group drift from its Unification Church roots into something more militant. It is a portrait of a small, heavily armed religious community built around the belief that faith and firepower are inseparable, filmed largely on its own compound.
