Handsome, charming Conor O'Shea has had enough of driving and guiding tours of Ireland. So when an opportunity to renovate and run the magnificent but rundown Castle Dysert as a five-star resort presents itself, he grabs it with both hands. But problems arise almost immediately when his business partner appears to have more on her agenda than just business. To add to that, his darling wife seems discontented as a stay at home mom, and his in-laws have moved in. With his family's future now entangled in a stunningly beautiful old castle on the coast of Clare, Conor undertakes a mammoth project, and in so doing, he uncovers the troubled past of this ancient stronghold. The mystery of the family who lived, loved, and lost their lives within the walls of the castle are reflected in his own family as they too struggle to let go of the past. Like in every small Irish village, gossip abounds. But do the ghosts of regret still haunt these ancient hallways? It is now left to Conor to explore the truth and uncover a heartbreaking lesson on the power of memory and the long threads that bind us together.
