The islands, surrounded by treacherous ocean, were once home to a community of people whose culture was untouched by outside influence. The cousins meet for the first time in Ireland on a quest to explore their shared heritage. They learn what has been passed down to them from those who came before and to surf the waters of their ancestors. Their's is a story of family, immigration and the value of tradition and culture.
