Martin and Sally Cramer are a well-off couple of thirty-something New Yorkers whose once loving marriage is now stuck in a rut. Martin works as the principal of an elite private school and the enthusiasm and rebel spirit of his youth are now long gone. However, Sally is still the hopeful idealist and optimist she always was and prides herself with her hard work as the English teacher in a grade school in an impoverished crime-ridden neighborhood, where she`s loved by the kids. They are both suffering from midlife crisis in a way, but they`re dealing with it in an opposite manner. Martin has become a depressed nihilistic mediocrity and he accepts it. Sally has become frustrated by the lack of effort from both her husband and some of her troubled pupils to make things better for themselves and others, but she still has some lust for life left. Eventually, she realizes that their marriage is going nowhere fast and decides to leave Martin despite being in the early stage of pregnancy.
