Appointment in Berlin

This wartime melodrama stars George Sanders as Keith Wilson, a disillusioned Britisher who becomes a "Lord Haw Haw"type at a Nazi radio station. All the time he's dispensing anti-British propaganda over the airwaves, however, Wilson is actually a secret agent in the employ of the His Majesty's government. It is Wilson's intention to use his intimate relationship with the Germans to expose a worldwide Nazi spy ring. (allrovi.com)
