Brunel's great ship, the Great Eastern, now lies beneath the mud, but Mark is resurrecting the story of her greatest triumph - how she conquered the Atlantic by connecting Britain's edge to America with two thousand miles of telegraph wire. And Andy Torbet tries to follow the footsteps of the sea shepherds on the island of Lewis, a style of farming that is slowing dying out.
