A young American, Frederick Winterborne, arrives in the small Swiss town of Vevey, where he accidentally meets a family of his fellow countrymen—Miss Miller and her children: nine-year-old Randolph and his older sister Daisy. The beautiful, self-confident girl not only captivates Winterborne, but also puts him before a dilemma he can’t resolve. Is she deliberately ignoring social conventions with her candid behavior, or does she simply know nothing about them?
