The cartoon begins with music from Music/RichardWagner's comic opera ''Die Meistersinger von Nürnberg'' before continuing into the title song:
->''(chorus) '''All''': When der Fuehrer says,\\
"Ve is the master race!"\\
'''All:''' Ve "Heil! Heil!" right in der Fuehrer's face\\
'''All:''' Not to love der Fuehrer\\
is a great disgrace\\
'''All:''' So ve "Heil! Heil!" right in der Fuehrer's face! (instrumental)''
A German oom-pah band composed of Nazi caricatures (a Japanese guy (Hirohito?) on sousaphone, a really, really, ''[[UpToEleven really]]'' [[CampGay flamboyant]] [[FatBastard fat guy]] (Göring?) on piccolo, an unnamed lanky man on trombone (Goebbels?), a big guy with SimpletonVoice on bass drum (Himmler?), and a little man (Mussolini?) on snare drum) marches through a small German town, where everything, even the clouds and trees, are decorated with the swastika, singing the virtues of the Nazi doctrine. Passing by DonaldDuck's house (the features of which depict [[UsefulNotes/AdolfHitler Hitler]]), they poke him out of bed with a bayonet to get ready for work. Because of wartime rationing, his breakfast consists of wooden bread, causing hiccups, coffee brewed from a single hoarded coffee bean, and a spray that tastes like bacon and eggs. The band shoves a copy of ''Mein Kampf'' in front of him for a moment of reading, then parades into his tiny house, bass drum, sousaphone, and all, and marches him off to a factory.
->'''''All:''' When Herr Goebbels says\\
"Ve own the world in space"\\
'''All:''' Ve "Heil! Heil!" right in Herr Goebbels's face\\
'''All:''' When Herr Goring says\\
"They'll never bomb this place!"\\
'''All:''' Ve "Heil! Heil!" right in Herr Goring's face!\\
'''Goebbels:''' Ist we not the Supermen?\\
'''Hirohito:''' [[AsianSpeekeeEngrish Aryan pure-a Supamen]]?\\
'''Himmler:''' Ya ve is the Supermen!\\
'''Goring:''' Super-duper Supermen!\\
'''Goebbels:''' Ist this Naziland so good?\\
Would you leave it if you could?\\
'''Hirohito, Himmler, and Goring:''' Ya this Naziland so good!\\
'''Mussolini:''' And-a we would-a leave it if-a we could!\\
'''Goring:''' Ve bring the world new order (blows on his piccolo)\\
'''Hirohito:''' (waving the naval flag of Japan) Heil Hitler's rule and order!\\
'''All:''' Everyone of foreign race\\
Will love der Fuehrer's face\\
When ve bring to the world his order!\\
Upon arriving at the factory (at bayonet-point), Donald starts his 48-hour daily shift screwing caps onto artillery shells in an assembly line. Mixed in with the shells are portraits of the Führer, so he must perform the Hitler salute every time a portrait appears, all the while screwing the caps onto shells, much to Donald's disgust. Each new batch of shells is of a different size, ranging from minute shells to massive shells as large as Donald, if not larger. The pace of the assembly line intensifies (as in the Creator/CharlieChaplin comedy ''Film/ModernTimes''), and Donald finds it increasingly hard to complete all the tasks. At the same time, he is bombarded with propaganda messages about the superiority of the Aryan race and the glory of working for the Führer.
->'''''All:''' When der Fuehrer says\\
"Ve never will be slaves!"\\
'''All:''' We "Heil! Heil!" but still ve work like slaves\\
'''All:''' While der Fuehrer brags\\
''And lies and rants and rave\\
'''All:''' Ve "Heil! Heil!" and work into our graves!'' ''(Heil Hitler!)''\\
'''All:''' When der Fuehrer yells\\
"I've got to have more shells!"\\
'''All:''' Ve "Heil! Heil" for him ve make more shells\\
'''All:''' If one little shell\\
should blow him right to [[CurseCutShort (Donald Duck gets hit in the head by a large shell)]]\\
'''All:''' Ve "Heil! Heil!"\\
And wouldn't that be swell! (instrumental)''
After a "vacation mit pay" that consists of making swastika shapes with his body for a few seconds in front of a painted backdrop of the Alps, Donald is ordered to work overtime. He has a nervous breakdown with hallucinations of artillery shells everywhere, some of which sing and are the same shape of the marching band from the start, music and all. When the hallucinations clear, he finds himself in his bed -- in the United States -- and realizes the whole experience was [[AllJustADream a nightmare.]] Donald embraces a miniature Statue of Liberty, thankful for his American citizenship.
The short ends with a caricature of Hitler's angry face. After two sets of "Heils", a tomato is hurled right in [[TitleDrop Der Fuehrer's Face]], forming the words "TheEnd."
->''(repeat chorus) (Hitler's face get hit with a tomato)\\
'''All:''' (slowly) So ve "Heil! Heil!"\\
Right in der Fuehrer's face!''
