In the countryside, a beautiful young blonde catches her lusty boyfriend cheating on her with her mother while her father enjoys the view, so she calls up her mother's lover to have sex with him out of spite.

Vanja is married, and has sex with Börje, who is also married. There's a bunch of other people having sex, with no clear connection to each other. There is some beautiful Swedish scenery from the archipelago and the woods, where everyone has sex, of course.
