No. 606 (Hurricane) Squadron has not recovered from the losses over Dunkirk when it is thrown into the Battle of Britain. As the losses mount, morale plunges. New pilots joining the squadron find a cold reception from the clique of Auxiliaries, who resent them taking the place of their dead friends.
Klaudia von Richthofen, a naive recruit to the Luftwaffe Women's Auxiliary, allows herself to be seduced by a dashing Stuka-Group commander-and then falls under the spell of the irreverent and carefree Baron von Feldburg. But it is his wingman, Leutnant Ernst Geuke, who has fallen desperately in love with her. Ernst, however, is short and plump and the son of a plumber from Cottbus, so how can he hope to win Klaudia's affection?
