Susanne Lamond, who earns her living as a cigarette girl in a cabaret in Paris, does not know that she is in fact a Hawaiian princess named Laya. Attaché Harald Stone from the United States falls in love with her and follows her when Liberation Movement agents lure her to Hawaii with a fake offer to perform as an artist. Here, according to the plans of the Hawaiian nationalists, she is to be married to Prince Lilo Taro, the pretender to the throne.
However, US Governor Harrison has a political agenda and plans to marry the prince to his niece Bessy to bolster US claims to the Pacific Islands. However, Bessy loves Harrison's secretary, Buffy. When the conspirators abduct Susanne to the old royal castle, where a big wedding ceremony is to take place, Susanne objects. She has long since fallen in love with the smart American and they both want to get married. She renounces all claims to the throne and titles and follows him. Eventually Bessy and Buffy become a couple too.
