After the Colonel makes René promise not to hang out with the Resistance anymore, Herr Flick's sausage (containing the forgery of the Fallen Madonna) is kidnapped by the Communist Resistance. The Colonel and the Captain are anxious that it doesn't come out that they have switched the paintings, and order René to come up with the ransom, which Edith gets from Monsieur Alphonse. The ransom is to be left by René and his staff, dressed as German soldiers. But the whole thing is watched by German soldiers dressed as French policemen, the Gestapo dressed as French Resistance girls, and the Colonel and the Captain dressed as trees. And of course, Lieutenant Gruber stumbles upon the meeting, and his dog can't help but chase the sausage. (thetvdb.com)
