Marie-Claire has just made the shocking discovery that her boyfriend (and business partner) is cheating on her. Reeling, she leaves her apartment in Toronto to travel home to Ireland, hoping the comfort of her family and a few familiar faces will ground her. She arrives just in time to celebrate her beloved great-aunt Reverend Mother Brigid’s retirement and eightieth birthday. It will be a long-awaited and touching reunion for three generations of her family, bringing her mother Keelin and grandmother Imelda - who have never quite gotten along - together as well. But then all hell breaks loose. Bitter, jealous Imelda makes a startling revelation at the party that forces them all to confront their pasts and face the truths that have shaped their lives. With four fierce, opinionated women in one family, will they ever be able to find common ground and move forward?
