After Maria is sent to Lieutenant Gruber with the sausage containing the real painting of the Fallen Madonna for copying, she is caught by General Von Klinkerhoffen, who places the sausage in his wardrobe and holds Maria hostage until his motor mower engine is returned by the Resistance. Herr Flick, the Colonel, the Captain and René hear about this and decide to go to the chateau through the secret passage and steal the sausage from under the General's nose, using Helga, Yvette and Lieutenant Gruber as a honey trap.
