Mira Sacky (Bessie Barriscale) will inherit a fortune if she is able to come up with ten thousand dollars for lawyers' fees. Since she has no money of her own, the only way she can think of raising the funds is to marry someone wealthy. When she gets the attention of Michael Ordsay (Jack Holt), she quickly asks him to marry her. It seems to be a mismatch, so Mira obtains the needed money from his kindly father (Tom Guise), and heads for Rome, where she undergoes voice training and becomes an operatic star.
While studying in Paris, Princess Oluf of Kosnia (Andree LeJon) befriends an American girl, Ruth Townley (Clayton), and gives her a locket bearing her name and the royal coat of arms. When Ruth accidentally drops the locket off a balcony, it is returned by a handsome stranger. Back home in Kosnia, Oluf wants to get married, but her choice of mate is challenged by Valdemir, the ruler of a neighboring principality (Warner Baxter).
