Flick,dragged up as Irma Von Kinkenrotten,the disguise he used to plant the bug,is still in the dungeon. Von Strohm and Von Klinkerhoffen,aware that he knows of the forgeries,feel he should be silenced and hatch a plan. The Resistance,led by Rene dressed as Himmler,will spring him. The German officers,dressed as Gestapo,whom they will blame if anything goes wrong,are to thwart the escape and put paid to Flick. However,the Resistance have effected the escape before the Germans arrive and they find only Rene,who has swapped places with Flick as the prisoner.
