France, late 1700s. Leon Dalville is a prince who has it all - good looks, love and wealth. One mysterious night, however, he loses everything. His young wife passes away in a fire and the prince’s face is permanently marred. To hide his disfigurement, he wears a silver mask that only partially covers his face, turning him into a mysterious and cruel man who is tormented by his past and hated and feared by all. Innocent and naive Bella Dubois comes to Leon’s castle to offer her services as a maid, to pay back the debts her father has with the prince. Leon’s cousin Helene, who has always been in love with him, challenges the prince: he must seduce and abandon Bella. But, despite Helene’s cruel and deceitful tricks, Leon falls in love with Bella.
