Gail Grant, the impetuous daughter of a Pittsburgh steel magnate, arrives at a hotel in Venice and demands the Imperial Suite; in London, George Banning-Green, a persistent admirer, believes that she has gone to Berlin. Searching for "imperial" furnishings, the hotel manager goes to the palace of Prince Dantarini, who is selling the contents of his villa as an aftermath of the war. Dantarini agrees to be her guide in Venice, and when he proposes in his garden, Gail accepts.
