Its focus is on Martin and Sally Cramer, whose twelve-year marriage is slowly disintegrating. He has become the stuffy headmaster of a fashionable Manhattan private school, while she clings to her dedication to the underprivileged and continues to teach in a ghetto public school. For him, their new high-rise apartment is a sign of their steady upward mobility; she is so unhappy with his need to earn and spend she moves all the antique furniture he has purchased to their first apartment on the Lower East Side. The growing chasm between them isn't helped by individual one-night stands, an unwanted pregnancy and consequent contemplation of abortion, an attempted mugging, and her racist cab driver father Joe Kaminsky.
