Caodaism began in 1926 in colonial Vietnam, blending Buddhism, Confucianism, Taoism, Christianity, and Islam under a supreme deity called Cao Đài, and within a few decades it had grown into the country's third-largest religion. The film traces that history through the war and the Fall of Saigon in 1975, when Vietnamese refugees carried the faith with them into exile, and follows its transplant into small communities scattered across the American Midwest. Interviews with practitioners cover the mechanics of belief and practice: ancestor veneration, the pursuit of spiritual development, and the rituals that mark daily and communal life. The film sits with the tension of a temple built for rice-paddy country now standing among wheat fields, and with congregants explaining how ceremonies, language, and community structures shift when a religion moves continents. With an estimated three million adherents worldwide, Caodaism remains largely unknown outside Vietnamese communities, and the film's plainest value is simply laying out what the religion actually holds and how it survives displacement.
