Documentary tracking the exploits of aging Calvinist preacher Fred Phelps, a convicted felon who leads his cult (primarily composed of his wife, nine of their children, and his fifty-two grandchildren) on their "love crusades" across America, which include calling for gays to be killed, praising terrorist attacks, mocking mourners at the funerals of AIDS patients and murder victims, and literally dancing and spitting on the graves of his enemies.
