Each of them is struggling with the weight of things unsaid.In the end, it's their father who, on the day of Rosie's wedding, exposes what has remained hidden for so long. And as the O'Connor siblings piece together the secrets at the heart of their family, they begin to forgive the woman who abandoned them all those years ago.
