Austria, Czechoslovakia, Poland, Holland, Belgium and Norway have fallen to the Nazis. In Paris, the government quails before Hitler and France prepares, confusedly, to be next. Two citizens, at least, are determined to not give in — a rich physics undergraduate who works on atomic fission, and her working-class chauffeur who is falling in love with her. Each in their own way fights back, with some touching, some disastrous, results. In stark contrast to France’s predicament at the beginning of the war, interludes follow an American GI on his way to Paris in the wake of the D-Day invasion, almost five years later.
