Boisterous, fun-loving, and popular Washington D.C. hostess Sally Adams is appointed U.S. Ambassador to the Grand Duchy of Lichtenburg, Europe's smallest country. In Lichtenburg, the Duke and Duchess are negotiating a political marriage for their niece, Princess Maria, in exchange for a substantial dowry. However, the country is desperate for funds and turns to the inexperienced ambassador for a much-needed U.S. loan. Sally refuses to discuss money—until she meets the ultra-charming General Cosmo Constantine. Meanwhile, Sally's press attaché, Kenneth Gibson, falls head over heels for Princess Maria.
