A barber in the court of King Louis XV, Monsieur Beaucaire (Bob Hope) falls in love with a beautiful maid (Joan Caulfield). When the king has had enough of the inept barber's shenanigans, Beaucaire is led to the guillotine where he is about to lose his head. Luckily for him, the Duc de Chandre (Patrick Knowles) rescues Beaucaire from his inevitable fate, transporting him to the Spanish court. However, when he later poses as a nobleman, it seems he may have pushed his luck a little too far.
