Vineyard owner Marquis Philippe de Montfaucon (David Niven) is called back to his castle Bellenac because of another dry season. He asks his wife and children to remain in Paris, but they still come after him. His wife Catherine de Montfaucon (Deborah Kerr) soon discovers that her husband is acting mysteriously and that his employees are following old pagan rituals that call for the life of the Marquis to save the crops.—Mattias Thuresson
