A successful, yet naive American woman, art critic Carol Cabbott, is married to German Eric Hoffman.

Eric's father, an elderly director and owner of a factory, tells them he wants to sell everything and leave Berlin, as he can no longer stand the hostile atmosphere.

Delane, who had hoped to get a leave to go back home, takes them to the station and tells Carol he has to stay "for the duration."

In 1940, New York Times reviewer Bosley Crowther called the "anti-Nazi propaganda film" "restrained", "frank and factual" and "generally entertaining cinematically".

"[1] A Variety review praised the film as a "powerful dramatic presentation" and Bennett's acting as "excellent as the educated American wife who sees through the schemes of Nazism, and provides much strength to a difficult assignment".
