In his first and only venture into filmmaking, Dutch comedy icon Toon Hermans tells the story of Jeep Moutarde. Mr Moutarde's house is threatened by the owners of the Knik Knak sausage factory who want to tear it down and build a sausage factory in its place. Fortunately, the other villagers — including a French wine seller, the village priest and Moutarde’s new love Helen, an English biologist — want to help him.

A man is attacked by all kinds of images from his past.

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. This film is presumed lost.
