Michael Portillo continues his journey through the Scottish lowlands with his Bradshaw's guide. He begins in the industrial town of Greenock from where he sets sail in the last seagoing paddle steamer in the world. In Glasgow, Michael investigates 'Mackintosh style' in an iconic city tea room, before seeing the devastating effects of the 2014 fire at the Glasgow School of Art. In Blantyre, Michael discovers the humble beginnings of Britain's most famous missionary and explorer, and learns to bake sour dough in Scotland's oldest bakery in Strathaven.
