Duke de Charres (Rudolph Valentino) is a French nobleman who escapes his warn-torn country in this costume drama. He settles in Britain where he becomes Monsieur Beaucaire and sets up shop as a fashionable barber. Lowell Sherman plays King Louis XV of France, with Lois Wilson as Queen Marie and Bebe Daniels as Princess Henrietta. Beaucaire becomes enamored with the beautiful Lady Mary (Doris Kenyon) and later reveals to her he is of noble blood. Watch for former Vitagraph comedienne Flora Finch as the Duchess de Montmorency. The excellent cast and the popularity of Valentino saved this plodding melodrama from being more than a routine feature.
