This romantic costumed adventure is the film that cemented Rudolph Valentino's reputation as a legendary screen lover. Sheik Ahmed Ben Hassan (Valentino) takes Lady Diana Mayo (Agnes Ayers) to his camp when he finds the beauty in the desert. Although drawn to the Sheik, Lady Diana is able to resist his amorous advances. When his former French school chum Raoul de Saint Herbert (Adolphe Menjou) convinces him to let Diana go free, she is kidnapped by the villainous Omair (Walter Long), who promises her a fate worse than death. The heroic Sheik and his army save Diana from suicide, but he is severely wounded in the melee. Diana helps the Sheik regain his strength after he saves her and she vows her everlasting love to her British-educated hero. Watch for seven-year-old Loretta Young in a bit part.
