Lubitsch's charming and gentle romance, set in Budapest. Klara Novak and Alfred Kralik have fallen in love -- but if they were to pass each other on the street, they wouldn't know: they've met only as pen-pals, and haven't even signed the letters with their real names. So when Klara applies for a job in the shop where Alfred works as head clerk, he turns her down cold... until his boss overrules the decision and takes Klara on. As the two continue their loving correspondence, they embark on a combative personal relationship. Will the hostilities cease when the truth comes to light? Or will their hopes for romance be destroyed forever?
