The Goose Steps Out

William Potts is an exact double of a German spy who the British have just captured. He is flown into Nazi Germany to impersonate the spy and instructed to seek out and bring back details of a new German secret weapon. Potts succeeds only in getting blind drunk and admitting he is a British agent. Luckily, some members of his class of Nazi youths turn out to be sympathetic Austrians and help him obtain the secret he seeks.
