In the 1930's, the "Pure White Cult" was organized. Gathering members with the promise of friendship, the founder was able to fleece his followers out of all their money. Female members served as the leader's concubines. When the cult faced exposure, the leader ordered 350 of his followers killed. Years later, Yu Gon-ryong reveals these facts to his father and sister, who have recently become devoted members of the cult which has resurfaced.
