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. When their honeymoon trip is postponed because of a business appointment, they quarrel, and she locks herself in the bedroom while he calmly sits down to dinner. After announcing her plan to divorce him, Gail bumps into Banning-Green and introduces him to her husband, whereupon Dantarini becomes violently jealous; when he offers her her freedom, however, her will is broken, and a word from Banning-Green sends them into each other's arms.
