Gewitterflug zu Claudia (1937)

Lufthansa captain Hans Droste is friends with English pilot William Crossley, who saved his life during the war. Having just landed in Berlin, Hans receives a telegram from his friend urgently asking him to fly to London and check on his dying uncle, Sir Reginald Crossley. Sir Reginald has only one wish: he wants to right a past wrong and asks Hans to find a girl to whom he wants to bequeath a third of his fortune.
