It's an adventure inspired by a single incident: the moment Billy received his Knighthood and was asked, 'How does it feel to have achieved all this when you came from nothing?' His response was, 'But I did come from something!' So begins an odyssey through the Highlands, the Lowlands and the Barrowlands on a shaggy dog quest to find out what that 'something' was and whether it is still there.
Far from a typical travelogue, Billy's quest is as much through his memories and experiences as it is through his excursions, with a series of key artefacts prompting reminiscences - a first pressing of a Hank Williams album (the first record he ever owned), Landseer's Monarch of the Glen, a bottle of air that re-creates the smell of the old Glasgow Docks - each of which inspire moments of reflection, joy, drama and laughter.
