After Granny wins a date with Daffy Duck in a charity auction, she makes him clean her attic. While the two are doing it, they find a World War II-era photograph of Granny as a foreign agent for the Allies. Granny proceeds to tell Daffy about the time she saved all of France's artwork from the Nazis. Her principal antagonist throughout the flashback portions of the episode is the single-minded, brutish Colonel Frankenheimer, an officer serving in the Wehrmacht Heer (Army) of Nazi Germany. Frankenheimer is first seen on top of the Louvre supervising the loading of several paintings onto his zeppelin and he laughs evilly, and when some of his men laugh, too, he hits them until they stop.
Granny snaps photos of the operation, catching Frankenheimer's attention and causing him to order his men to capture her. She flees to the Eiffel Tower, where she gives the film from her camera to Tweety, but as he flies away, Frankenheimer's zeppelin appears overhead and he uses it to lift up the entire Eiffel Tower, proclaiming it France's greatest work of art. As the Eiffel Tower is lifted, Granny falls off, but she is rescued by Tweety, who flies her around. Frankenheimer, spotting them, orders his pilot to shoot them, but the pilot misses and hits part of the zeppelin frame accidentally. Enraged, Frankenheimer takes the pilot's gun and then throws him out to his death, and tries shooting Granny and Tweety himself, but can't get a bead on them before they fly up and land on top of the zeppelin.
Climbing up to confront them, Frankenheimer is unable to shoot Granny, who knocks the gun from his hands. She demanded he land the zeppelin, but he refused, sneering that he didn't take orders from women, prompting the two to engage in a fistfight. Frankenheimer won, knocking Granny off the side of the aircraft, but she clung by her fingers. As Frankenheimer tried to kick her off, Tweety appeared, tying a rope to the Nazi colonel's ankle and punching him. He fell off the side, but his descent was halted by the rope around his ankle and he banged against the hull, knocking himself silly.
Later, when the Allies liberated Paris, a very dejected-looking Frankenheimer was turned over to the French authorities and taken away to prison..
- His name is a reference to John Frankenheimer, who directed the movie The Train, which Granny's story is clearly based off of, making Colonel Frankenheimer a parody of the film's main villain; Colonel Franz von Waldheim.
- His stealing priceless French artwork makes him similar to such Nazi villains as Colonel Franz von Waldheim (another reference to The Train) and Major Schultz.
- His escape aboard a zeppelin is similar to Neville Sinclair in The Rocketeer, while his fight with Granny on top of the aircraft is similar to Lothar's fight with Cliff in the same film, right down to Frankenheimer being knocked over the side while tied to the zeppelin.
- His uniform looks like the Colonel of the GDR, rather than the Wehrmacht.
