In the final episode of the series, Paul visits Kintyre and encounters a strange and spiritual cave painting on Davaar Island, before sampling spirits of another kind in Campbeltown, famous the world over for whisky. This leads him to uncover the story of the only coal mine in the Highlands and a seam that runs all the way to Ireland. Heading up Loch Fyne, Paul joins the last of the Ring Net fishermen onboard a restored fishing boat heading to Lochgilphead, where he tracks down the inventor of Scotland's lost supercar - the Argyll Turbo. Journey's end is in the middle of Loch Fyne on a truly remarkable relic of the Ice Age.
