A young American woman traveling in Italy with her mother is slender, blonde, beautiful and there is something charmingly naive about her. Fabrizio Naccarelli seems to always know where the mother and daughter will sightsee next. Signor Naccarelli is just as concerned about where this will lead as Mrs. Johnson is. Then she starts thinking that perhaps her daughter can be a wife of a wealthy young man in a society where all she has to do is look beautiful. What happens if Signor Naccarelli finds out who his prospective daughter-in-law really is?

Revealing mistakes: When Mrs. Johnson walks around town on her own, just before she decides to go to the US consulate, there is, at one point, a clearly visible crowd of onlookers (and a man trying to keep them back by spreading his arms) in the background. There is nothing about the place or the circumstances that could explain their attitude; they are clearly all watching the shooting of the film.
