To pay off her stepmother’s huge debts, Eva is forced to take her stepsister’s place and marry into an ancient, eerie noble family rumored to doom every bride to an early death. The wedding is lavish yet shrouded in gloom. Her cold, handsome groom and the family’s bizarre mannerisms feel like part of a prearranged sinister ritual. On their wedding night, Eva stumbles into the manor’s basement and finds a chained woman in white who looks exactly like her. The woman reveals she is the real intended bride, and Eva is merely a substitute meant to bear the family’s fatal curse. As strange incidents pile up—missing maids, an eerie family tree, old wedding photos—the horrifying truth unfolds: for years, the family has played a cruel deadly game with their brides. The aloof groom watches seemingly indifferent, yet secretly protects Eva time and again, leaving her unsure if he is an accomplice or the only keeper of the secret. Cornered, Eva digs deep and discovers both women are pawns. The forced substitution is a bloody plot to select controllable heirs and secure the family fortune. In the end, Eva breaks free from fate. She burns down the manor along with all its dark secrets, shattering the cruel curse that has haunted the family for generations.
