The parody begins with a recap of the previous parody where Fegelein kills Hitler for watching scat porn and takes over as Führer. He decides to throw a celebration where he is congratulated by Himmler. When asked what he will do, he says that he plans to "finish what we started". He plans to do an antic that will possibly end the war, trick the Russian generals & soldiers into seeing a shock website that will traumatize them into a coma. Krebs volunteers to do so due to his ability to speak Russian and knowledge of a certain website (*You'll see*).
Krebs proceeds to the Russian generals, telling them of Hitler's death and proposes a "truce meeting", which they agree to come. Several hours later, Fegelein gets a report on the antic being highly effective, winning the German army the war. Fegelein then tells everyone to get some rest so they can eventually rebuild.
Meanwhile in a different yet identical bunker, Speer (with assistance from Herbert West) has apparently brought Hitler back to life. Now that Hitler is alive, he reminisces a time where Fegelein was committing antics that were cruel, but tolerable – the scene flashed back to Hitler's 54th birthday party where Fegelein gives Hitler a fake dog turd without him knowing at first. He also tells about a time when he was shot in the groin by a kid in World War I. Afterwards, Hitler asks how is everything back in the bunker and Speer tells him that Fegelein is now the Führer. Hitler, after snapping a pencil in half, decides to return to the bunker and kick his ass.
After phoning the bunker telling them that he's coming for Fegelein, Hitler and Speer ride across a landscape on motorcycles. When there's chatter of Hitler coming to the bunker, Fegelein attempts to reassure everyone that Hitler is dead, explaining that "you can't survive a headshot." Eventually, Hitler does make it to the bunker as everyone, but Fegelein, leaves so that they may fight it out.
They meet up in a back alley where they each throw a punch at each other. Then, Fegelein reveals that he was the kid who shot Hitler in the groin in World War I beginning the fight. As the fight went on, some Soviet women enter the bunker and an engineer approaches them. He explains what is going on and asks why they're here. They explain that they're here for the "Lemon party" (Apparently, they believe that 'lemon party' is code for 'golden shower'). Back at the fight, Hitler and Fegelein are on the ground slamming each other. Fegelein then mounts Hitler and repeatedly knees his last testicle until he squashes it causing Hitler's voice to change making him sound like a chipmunk. Eventually, Fegelein wins the fight as he goes over to rest... only to get body-slammed by Hitler.
Afterwards, they all have dinner as Hitler tells Fegelein that he was going to have him executed, but decides to make him Tactical Advisor due to an antic he created to win the war and also the Close-Quarters trainer. When Goebbels asks Hitler what he will do now with no testicles and a high-pitched voice, Hitler explains that he had Günsche go get testicles from a crotch donor and also hired one of the generals to do the surgery, but remains private about who it is.
We learn that it was Grawitz who was hired to do the surgery. After explaining to Hitler on what to do, he asks why he hired him to do the surgery, Hitler tells him that if he does it, he'll give him a promotion. Then, Günsche comes in with the testicles as they are about to begin the surgery before the end credits start.
After the credits is a quick scene with Hitler telling Fegelein that he can be Führer again. Hitler give his thoughts on the parody as he calls it, "The worst piece of shit I've ever seen!" He says that Fegelein being the Führer is the worst concept of all time, but he states that he likes the parts where he's beating on Fegelein. We end with Fegelein giving his opinion on the parody calling it pretty decent.
