The Gestapo suspects that the Colonel and the General are in on a plot to assassinate Hitler, so Herr Flick goes undercover as Private Irma Von Kinkenrotten and plants a somewhat bizarre daffodil-shaped microphone in the Colonel's office, where Gruber and Von Strohm are making plans to get rid of Bertorelli in some way.
Meanwhile, as Edith prepares for her wedding, Rene and Co. must get the aerial for their new radio above the jamming signal of Herr Flick, so they disguise Mimi as a small nun to obtain a box kite which they fly to contact London and request plastic explosive to blow up the safe in the General's chateau to get the British Invasion plans.
