After many years of separation, Janne (Maria Bonnevie) and William reunite and rekindle the playful love and friendship they shared in their youth. They leave their families behind, move to a cabin by a river, frolic naked in the woods, screw on the regular, and then swim naked until they get tired and do it all over again. Also, they're being haunted by William's brother or something, but that doesn't sound too bad.
