Banjo has been commissioned by married couple Jhennia and Rachel to transform the Puffer Pub on the tiny slate island of Easedale. The historic pub is the beating heart of Easedale's population of just 60, so Banjo's design needs to hit the mark with the locals and the owners. With no roads and only wheelbarrows to transport all his materials, this makeover will be very challenging. Lisa, Eoghan and Tom race against time to complete his ambitious designs, but will his radical idea of replacing the decades-old bar meet the approval of the locals, and can he complete the work ahead of the World Stone Skimming Championships?
