The town of Greenville, Utah, is dominated by the Septosect religious cult and its leader Harrison who has ambitions for increasing his religious control over the area. Living amidst the threat of a fatal virus, which could take a whole horde of people at a time, the members of the cult look to the Septosects ideals as a way of life, hoping that a divine entity will spare them from their doomsday. They are trapped by Harrisons reminder that leaving the town would mean divine condemnation.
Deception about the virus, fake news and religious fervour keep the community isolated, but the death of a young girl leads to suspicions over the motives of Harrison. Living amidst the virus makes life feel desperate for Greenvilles community members, who feel that each passing month is precious but futile. The cult members must choose to believe if the seven principles of the Septosect will lead them to the truth, or to their deaths.
