Everything changes for Kate, Moya and Romy when they receive word that Maeve Dillon, their mother, is critically ill. It is time to return from Dublin, London and New York to Rossmore and the old stone house overlooking the Irish Sea where they grew up. But ancient jealousies surface as each sister confronts the past and the decisions they have made. For work-driven Kate it is time to take stock of her role as a high-flying ambitious lawyer and single parent; life is a battle between work and looking after Molly with little time for a proper relationship. Even Patrick, the man she once fell for, has ended up marrying her sister. Beautiful and intense Moya must take a hard look at her marriage to the charming but unfaithful Patrick and consider her own worth. For wild child Romy who has travelled the world and hasn't put a foot on Irish soil for years, it is time to finally stop running and find the courage to confront her family. A good and caring mother, Maeve Dillon has somehow over the years labelled each of her three daughters- Moya the beautiful, Kate the brains, and Romy, the bold and wild one. Now it is finally time for all three to break out of the box.
