Tre må man være

A lawyer has a wife and a mistress. He loves them both equally high and together, they're the perfect wife. Lawyer Peter imagines that he has arranged himself perfectly. His wife Elisabeth is sweet and orderly, and his lover Kate is messy and erotic. When his friend Johannes comes to visit, he launches a campaign to make Peter realize that his life is a mess. But in his attempts to clean up, Peter completely forgets that the women also have something to say.
