A one-joke movie: a family of bourgeois boys (Pop and sons) retire to the country house for a short holiday that ends up lasting for years. They take turns screwing the maid, strolling the grounds, etc, until all they want to do is sleep: most of the day, then most days of the week, then for years. The horror of getting out of bed is just too much. And that's it. That's the movie. All two hours of it.
