The Irish border is currently the focus of intense negotiations around Brexit. Nobody knows how a soft or hard Brexit will work in practise but most agree that a hard border will negatively affect both the economies and relationships of the Republic and Northern Ireland. Helen Mark delves beneath the politics to discover the wildness of the land along the border and talks to the people who live there and cross the border daily. The border has inspired artists and writers such as Garrett Carr and Rita Duffy and Helen meets them to explore the borderlands and try to understand the unique history of the places along the line from Lough Foyle to Carlingford Lough.
