It´s 2018 and an invading army of moon-dwelling Nazi shock troops is about to launch an attack on Earth with the aim of yoking human slave labour to a Fourth Reich. And there´s worse - Sarah Palin is in the White House.
Finnish maverick Timo Vuorensola´s enjoyable sci-fi comedy revels in superior special effects - the swastika-shaped moon base and the ultimate Nazi doomsday weapon The Götterdämmerung are awesome creations - and a knowing if broad script.
Götz Ott - replendent in his ersatz Hugo Boss uniform and bearing a nice sardonic sneer - is well cast as the fanatically ambitious Nazi General Klaus Adler while Julia Dietze is just so as his blonde Hitler madchen fiancee-turned-adversary Renate Richter.
Elsewhere, James Washingon delivers good Samuel L Jackson as the black American astronaut despatched to the moon to push Palin´s re-election hopes, captured by the lunar goosesteppers and turned white by a mad German professor.
Udo Kier, who faced a similar alien invasion in Armageddon as a NASA flight surgeon, plays the veteran Nazi commander-in-chief who has to constantly look over his shoulder for the ambitious Adler.
A scarily power-crazed Palin is lampooned mercilessly and America's gung-ho foreign policy is given a gentle ribbing that morphs into something altogether darker as the final credits roll.
However, what will impress audiences most are the first-class battle sequences featuring a splendidly retro Nazi attack force, including supercharged zeppelins, which takes the original German military hardware and gives it a neat yesteryear spin.
Impressively financed while it was being made and marshalling support with an efficient social media campaign (£1m of the £10m budget was raised online), it´s a stunning reminder that often less is more.
