Christina Trevanion and James Braxton's antique explorations continue in the cold and snowy Trossachs. Christina's five vests do not impede her hunt for treasure, while James hopes a foxhound will sniff out a few pounds profit at auction in Bolton, Greater Manchester. The 1965 Jaguar purrs all the way to a graveyard in Glasgow, where James investigates some ancient treasures, but not before farmer's wife Christina learns why it was the Scots who transformed arable farming.
