The board of directors of Hell want Satan to resign and replace him with Hitler. The Devil refuses to go and insists that Hitler isn't all bad and that he will prove it by having him perform a good deed. Heading up to Germany Satan gets himself in with Hitler and then sets about getting him to do good, while at the same time having to deal with Mussolini and the Japanese General Suki Yaki.
Odd running time aside, it's a streamline feature running about 43 minutes, this is an odd film. Its a very odd feeling watching the Devil run around trying to prove Hitler isn't all bad, especially when he uses examples of Hitler's cruelties that are actually much worse in retrospect than what was known when this film was made. In its way the film is almost an exercise in bad taste as a result of the revelations that followed.
But lets not dwell on the bad, lets talk about the good, this is an amusing little comedy. For the most part this is a series of set pieces and running gags concerning Satan masquerading as Hitler, the backstabbing and double dealing of the Axis "allies" and the insanity of Hitler. While many of the jokes will not be new to anyone who's seen comedies of the period, especially the Three Stooges classic rips at Hitler, they are funny and will produce smiles if not chuckles and giggles. The performances are right on target and engender a great deal of good will simply because they are so silly. And while some of the gags do go on much too long with out a really big pay off (they were stretching even to fill 43 minutes) it never wears out its welcome.
Worth a look if you run across it.
