The Communist Resistance steal Herr Flick's sausage (containing a forged copy of the Fallen Madonna) from the cafe, demanding a ransom for its return.
Maria is sent to the chateau with a knockwurst, containing the real painting, concealed across her bosom for Gruber to create another forgery.
Von Klinkerhoffen intercepts her, hangs the sausage in his wardrobe, and sends a message that she will remain in his rooms until his lawnmower engine is returned.
As word gets around of their location, the cafe staff, Gruber, and the Gestapo enact their plans to retrieve the sausage and rescue Maria.
General Von Klinkerhoffen commandeers their services for the chateau, along with a painting behind a curtain, which contains the Fallen Madonna inside.
