The film portrays a tragic love story set in late 1930s Ireland, focusing on the relationship between Fiona Flynn (Moya Farrelly), a beautiful, feisty seventeen-year-old from a middle-class family, and Kieran O'Dea (Aidan Quinn), a shy labourer in his early thirties, and the search decades later by their son, Kieran Johnson, (James Caan (actor)) to find his roots in late 1990s Ireland.
