The archduke's grandfather wants to thwart the love between Princess Erzsébet and András Balogh, a young man of lower rank. He sends Erzsébet to Switzerland and András Balogh to Warsaw as an embassy secretary. However, Erzsébet follows András to Warsaw, where they both become embroiled in criminal complications when András has to return home with important diplomatic documents. Back home, it turns out that everything happened so that Erzsébet could soften the archduke's grandfather's heart and rescue András from the predicament he got himself into for Erzsébet's sake... The film is set in Warsaw, and the exterior shots were taken just before the outbreak of World War II, so the film still shows Warsaw intact.
