Lt. Hanley is pulled off the line and sent to London, where he is assigned to a secret mission to aid a French physicist to escape occupied France before the Gestapo captures him. Hanley once spent the summer in France at the family's home and is the only man the scientist will trust - especially since it has been discovered that someone in the French resistance is a double agent.
