Le Prince charmant(1925)

Unkwown to the vast majority, Count Patrice is the crown prince of Simenia. One day he sails for the East on his yacht "Bengal" in the company of Christiane, a beautiful princess, in love with him. Chance has it that Patrice sets Anar, an Oriental beauty, free from the harem where she is held captive. Love is born between the two young people, which infuriates Christiane. Mad with jealousy, the vexed woman sets about preventing Patrice and Anar from marrying... by all means fair or foul!
