New York, 1963.
For four young women, brought together by the impossibly small Upper East Side town house they share, it is a time of possibilities, of things to come. A time of newfound freedom, of careers their mothers never considered, of imagining lovers into husbands and families of their own.
Leigh, Cady, Vanessa and Susan. Although their dreams are different, they share secrets and fears, high spirits and higher hopes. But as the world around them changes, the decisions they make in that fateful year are challenged. Each on her own path, they will learn that friendship can shift in unexpected ways, that love is more complex than they imagined and that happiness is sometimes found where they least expect it.
