is a 1946 American war spy film directed by Irving Pichel and starring Alan Ladd, Geraldine Fitzgerald and Patric Knowles.

Produced and distributed by Paramount Pictures, it portrays the activities of the Office of Strategic Services during World War II.

The screenplay was written by Richard Maibaum, a World War II veteran who would later write twelve of the first fifteen James Bond films.

Caught and arrested for espionage, he is turned over to the Office of Strategic Services, which is training a group of new recruits by sending them on test missions.

Along with three other men, Gates, Parker and Bernay, and one woman, Elaine Dupree (Fitzgerald), Martin (an assumed name like the others) is sent to France to blow up a railroad tunnel in order to paralyze Axis troops during the Allied invasion.

Elaine sculpts a bust of Meister's head, and when he announces his departure for Normandy on a troop train, she begs him to take her with him.

As the Allies break through at Normandy, Elaine and Martin make a deal with Amadeus Brink, an officer of the Gestapo, who hopes to secure his safety and a small fortune.

Brink removes Martin and Elaine's "wanted" file from the Gestapo sector headquarters and arranges for his cousin, a courier, to hand over a diplomatic pouch to Bernay for photocopying.

As the American troops advance through France, Brady tells Martin that Elaine's real name was Ellen Rogers, and he imagines that she might have been the girl next door in his hometown.
