The plan to photograph the plans for the German invasion of Great Britain goes bad when Edith puts the smoke bomb in the wrong chimney of the château, and René and LeClerc are forced to blow up the safe in another kind of chaos than they had original... (more)ly planned. During the escape, René and LeClerc are captured by the Communist Resistance. Helga is ordered by the Colonel to be Lieutenant Gruber's best friend, but during their not-so-romantic tête-à-tête, Edith and the servant girls steal the Lieutenant's little tank to try and rescue René.
