Cormac and Breanndán Ó Beaglaoich come to the end of their journey up the west coast of Ireland in Donegal, where the Begley clann left in the 17th century for the Battle of Kinsale. They kick off their homecoming with their old friend Steve Cooney in Teelin. Shauna Mullin and Damien McGeehan hop into the van for a stunning performance in Glenties. They get a taste of Donegal fiddle music from the Campbells. Breanndán is reassured that tradition will live on by An Crann Óg before reaching their homeland of Tullaghobegley.
