Meet Richard and Barbara Harmon. A typical American couple, together for 17 years. But lately things have gotten too predictable and stale. The once loving couple spends their evenings arguing, their marriage quickly unravelling. They visit a marriage counsellor to no avail, and when Richard pays a drunken visit to a prostitute (Lee Grant), they split up. But the Harmons find their newly-single lifestyle isn't going to be easy. Richard meets Jason Robards who plays matchmaker for his ex-wife Jean Simmons, figuring he won't have to pay alimony if she's re-married to Richard. Barbara falls for Big Al (Van Johnson), a car dealer with a mother fixation. But when Barbara and Richard are reunited at a nightclub one evening, they come to the realisation that even though they didn't have a perfect marriage, it was a lot better than their 'divorce'!
