Princess Ann (Audrey Hepburn) is representing an unnamed European country on a continental tour. Her latest stop is Rome, and that's where she has a meltdown. When her secretary confronts her with her schedule for the next day, she has a fit of hysterics - she's fed up with having every moment of her life planned. The doctor arrives and gives her a shot that makes her sleepy and happy. In her drugged state, she slips out of the palace and into the city, where she poses as a drunk, homeless girl. Reporter Joe Bradley (Gregory Peck) finds her and, feeling guilty about abandoning someone in no condition to be on her own, he brings her back to his apartment so she can "sleep it off." The next morning, he discovers the identity of his mysterious guest and begins plotting how he can get an exclusive story out of the situation. He enlists the aid of his friend, Irving Radovich (Eddie Albert), to take the pictures. Over the course of the day spent with Ann, Joe's desire to write the story wanes as his affection for his companion grows.
