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 Klinckerhofen, who places the sausage in his wardrobe and helds Maria hostage until his lawn mover engine is returned by the Resistance.

Herr Flick, the Colonel and the Captain, and René hears about this and decides to go to the chateau through the secret passages and steal the sausage from under the General's nose, using Helga, Yvette and Lieutenant Gruber as erotical bait.
