When Colonel Klink boasts that the Nazis' new Tiger Tank will lead the Germans to victory, Colonel Hogan devises a plan to get his hands on one of the vehicles, have it disassembled, send its blueprints to the Allies, and reassemble it --- right under Klink's nose.

To prevent Colonel Klink from being transferred to the Russian front, Hogan and his men attempt to convince a visiting Inspector General that the Colonel is a cold, heartless disciplinarian. But their plan backfires when, as a result, Klink is promoted to a post in Berlin!

Several attempts by Hogan and his men to destroy a German bridge end in failure --- until they decide to use the Nazis' own ammo to accomplish the task!

Sergeant Schultz, while escorting Newkirk to the dentist, gets drunk and is replaced by a hard-lined, no-nonsense guard. Hogan and his crew must act fast to get the docile Schultz restored to his post.

Can Hogan locate the secret German air base commanded by a World War I flying ace known as the Blue Baron? Yes --- by convincing Colonel Klink to throw a party for the famed aviator.
