In this true story that takes place in the deeply religious Italy of the 1960s, former actress Anna Fallarino and millionaire Marquis Camillino Casati use their private island Zannone for lust-filled, alcohol-fueled orgies with European nobility while the Marquis also solicits young men to have sex with his wife and photographs the encounters. Their secret life soon leads to tragedy after Anna falls in love with another man.
