The Team travel to the windswept island of Barra, 50 miles off the west coast of Scotland, for a unique rescue dig. This Hebridean outpost is famous for its strip of unusually fertile sand dunes all round the coast, land that has been home to settlers for the last 4,000 years.

When a storm ripped apart one of the dunes, it revealed Bronze Age graves and the remains of ancient houses. The team must also work in the face of the fierce Barra winds to preserve a collection of Iron Age ornaments before they become lost forever, including the remains of a cooking pot, and tools crafted from animal bones and whale rib.
