She takes the next ferry to Dublin to identify her daughter, Kate, who disappeared 20 years ago. Consumed by grief, Colette resolves to stay in Ireland to work for the Garda, while also piecing together the truth about Kate's death. If she did fail her daughter in life, Colette is determined to do right by her now – but is she prepared for what she finds?
