When Susanna's car gets a puncture, she gets help from Nate. Nate reappears in Susanna's family's garden store where she works. He wants her to put her training as a landscape architect to use with Mrs. Waller whom he is visiting. The romance blossoms, but little does Susanna know that Nate is in fact a prince on the way to becoming king in a small European country where tradition dictates that the king should marry aristocratically.
Another movie with a prince from an unknown small country in Europe (where are all these countries located?). Perhaps somewhat better than several of the other films on the same theme but still…
