Berlin Correspondent (1942)

An American radio correspondent is reporting from within Nazi Germany. His principal source of information is an elderly philatelist. His reports prove so embarrassing to the regime that Captain von Rau sends his own fiancée, Karen Hauen, to compromise the reporter. As the philatelist is sent off to a concentration camp, it develops that she and the reporter are falling for each other, and the elderly source was actually her own father.
