Made just before America's entry into World War II, Paris Calling is one of the earliest French Underground adventures. When the German march into Paris, a polyglot of French patriots organize to undermine the Nazi occupation troops. Marianne is a French aristocrat who learns that her ex-fiance Benoit is a collaborator; she agrees to help the Underground, even unto killing her former lover. Colette, normally a villain, is sympathetically cast as a blowsy waterfront entertainer whose waterfront dive serves as Resistance headquarters.
