Michael Portillo embarks on a new journey through southern Scotland from west to east. From Ayr, he admires the granite island of Ailsa Craig before getting to grips with the ancient sport of curling, with help from a Scottish world champion. The Ancient Society of Kilwinning Archers invites Michael to take part in the oldest archery competition in the world. At Barassie, he rides the footplate of a freight train hauling coal on Scotland's oldest railway line. He caps off this leg of his journey in Stewarton.
