A friendship between college graduates Harry Burns and Sally Albright precludes Harry’s conviction at the first meeting of the two in 1977 that men and women can never be friends. Over the years, both fail with their partnerships and by chance, the two meets again after five years.
And after another five years. Since both have a failed relationship behind. When they start talking, they learn that they are both separated from their partners. They make appointments, make long phone calls and become friends. Attempting to marry each other causes their friends to fall in love.
