The show opens during the air raid which ended last episode - Rene is running back to the Cafe, and Von Klinkerhoffen, Von Strohm, and Bertorelli are all hiding under their desks. Herr Flick continues interrogating Helga about the plot to blow up Hitler. Herr Flick and Von Smallhausen disguise themselves as the musicians to discover whether Von Klinkerhoffen is truly blowing up Hitler. Michelle devises a plan for Rene and Leclerc to break into Gruber's room during a smoke bomb diversion disguised as firemen and blow the safe. But Edith and Yvette pick the wrong chimney down which to throw the smoke bomb, instead hitting Von Klinkerhoffen's chimney.
