Long journey for recognition of Travellers' ethnicity

In the 1992 film Into the West, two motherless Traveller boys, Tayto and Oisín, live in a grim tower block in Ballymun with their father, a former Traveller ‘King’.
When the boys’ grandfather, a traditional Traveller who regales the spell-bound children with Irish folklore, is followed home one night by a beautiful white horse called Tír na nÓg (‘Land of Eternal Youth’ in Irish), the boys dream of becoming cowboys.
