When Mister Vlasman gets promoted from baking bread to making macaroni, he and his wife want to enter high society. They could not be happier when a wealthy baron offers to introduce them into the high class. What they don't realise is that this was all an April Fools' prank. Unfortunately for the pranksters, things get out of hand when a real baron visits the Vlasmans.
The movie is a remake of the German film April, April! (1935), also directed by Douglas Sirk. In the German version the baron was a prince. Sirk never came to the Netherlands. All of his scenes were shot in Germany. Scenes in the Netherlands were directed by Jacques van Tol. No known copies of the film exist today.
