Max Tracey is the head waiter at a London hotel. He falls in love at first sight with Sylvia Robertson, an aristocratic woman, and poses as a prince to win her love. In this venture, he is aided by Mr. Westlake, a Ruritanian monarch who owes him a favour. When Sylvia discovers Max's deception, she is appalled, but the situation is resolved when her father tells her that he was once a hotel dishwasher.
