Archaeologist Ben Robinson visits a small village in Northumberland to find out how the family and village who both share the name Craster have had their lives and fortunes intertwined for over 800 years. The village sits on a unique seam of rock called the Whin Sill and next to the North Sea. Ben learns how, through the generations, the Crasters have used local resources to make their fortunes and in turn have changed the face and the fortunes of the village and the villagers.
