As he lies dying, Count Florian Zuleski of Poland, the head of a committee working for perpetual peace among European nations, entrusts his daughter, Mayra, with the dangerous mission of delivering some important documents to New York. Arriving in the United States, Mayra is unable to establish contact with the Polish representative and goes to live with her aunt. She soon meets Brian Kelly, who is working as a traffic cop after being disinherited by his irate millionaire father for not entering into a marriage of convenience with patrician Janet Van Wyck.
