The White Cliffs of Dover
It tells the story of an American girl who travels abroad to England and falls in love with an English aristocrat. The girl marries the Englishman but their honeymoon is cut short on its first day as World War I breaks out. The husband goes to war in France, sees his bride only once more and then is killed in action near the end of the war. In the meantime the wife has his son, that she raises along with the father's mother. A scene in the movie approximating the early 30s shows adolescent German boys, part of an exchange program, visitng the English family's country estate. Insinuating they were part of early Nazi invasion plans, the movie has the boys let it slip in conversation that they are contemplating how the estate's large lawns would be ideal for troop gliders to land on.
