The show opens during the air raid which ended the last episode - René is running back to the café, and von Klinkerhoffen, von Strohm and Bertorelli are all hiding under their desks. Herr Flick continues interrogating Helga about the plot to blow up ... (more)Hitler. Herr Flick and von Smallhausen disguise themselves as musicians to discover whether von Klinkerhoffen is truly planning to blow up Hitler. Michelle devises a plan for René 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.
