Barra is in Greenore, on the shores of Carlingford lough. He’s here to meet local man Shane Reenan to help solve the mystery of where Finn, a solitary bottlenose dolphin that has taken up residence in the lough, has come from. Barra then heads to Carlingford, where he hitches a ride out onto the lough at low tide to work on the oyster beds. Finally Barra heads to the Ring of Gullion where he meets Caóilfíonn Murphy O'Hanlon, an artist passionate about celebrating and protecting our only native goat, the Old Irish Goat.
