A professor's wife finds out he's having an affair, and at the same time falls in love with a female professor. The story of three men and the one woman that they share from the time they are children and throughout their lives. It does look like the three main characters are getting set to stay together at the end of the movie. Light-hearted romp about a man who gets himself married to two different people. When everyone finds out, they try to share.
Bad things happen.
Due to the scarcity of women, Marvin and Eastwood share one. Then he meets her other lover. Alda plays a politician who falls in love with another woman at a convention. Instead of breaking it off, they decide to share him without his knowledge. Low-budget production, but asks good questions.
