It's the 1990s. Jane and Jonny Molin own the campsite "Fredriksdals Trivselcamping." Last year, the campsite received the "award" for trash can of the year. If they receive it again this year, they will lose the campsite, so now they have to find that inspector, the one who travels incognito. If they just suck up to him enough, they might even get the "golden tent peg" instead of their rivals Gulli and Bill Hilding. They suspect one guest after another at the small campsite, while their son Allan just sighs; he has no intention of helping, no, he wouldn't want to take over the campsite anyway.
