The Four Seasons (1981)

Middle-aged couples Jack and Kate Burroughs, Nick and Anne Callan, and Danny and Claudia Zimmer are best friends who do everything together. As couples, they have weathered the flood of divorces that has beset their other friends. When one of the six decides to make a change in life, the other five are forced to examine their marriages, their friendships with one another, the true meaning of love, and their own personal foibles. Over the course of one year, the movie is set against the backdrop of four vacations they take together, one in each of the four seasons, with Antonio Vivaldi's associated suite of music introducing each. By their fourth vacation together, Jack feels that they need to "clear the air."
