Nora and Theresa Flynn are 21 and 17 when they leave their small village in Ireland and journey to America. But when Theresa ends up pregnant, Nora is forced to come up with a plan --- a decision with repercussions they are both far too young to understand. Fifty years later, Nora is the matriarch of a big Catholic family with four grown children. Estranged from her sister, Theresa is a cloistered nun, living in an abbey in rural Vermont. Until, after decades of silence, a sudden death forces Nora and Theresa to confront the choices they made so long ago.
