Robson travels to the wild and remote coastline of the Outer Hebrides and discovers how an unpredictable climate has given these islands an identity and way of life of their own. At the ancient village of Gearrannan, Robson tries his hand at weaving Harris Tweed in a traditional crofter's blackhouse, with mixed results, and on the Isle of Lewis he goes snorkelling for sugar kelp, used to flavour the local gin. He also camps on the beach at Luskentyre, and on the Isle of Barra helps out at the airport, where the beach doubles as its only runway.
