The actor meets people who share his passion for the British coast, beginning with north Devon, a 90-mile stretch of shoreline that holds fond childhood memories for him. Robson starts his adventures by visiting the popular seaside resort of Ilfracombe, a town that stills attracts thousands of visitors every summer, to experience the classic British day out by the sea. After spending a night under canvas, he takes a boat ride to the port of Clovelly, a village that evokes the character and atmosphere of a bygone age, and visits the island of Lundy.

The actor explores the hidden coves and remote islands of Pembrokeshire and meets up with former Soldier Soldier co-star and singing partner Jerome Flynn - who is now living on the coast. They go sea kayaking around Ramsey Island and Robson attempts to navigate some of the most dangerous tidal rapids off British shores. On Skokholm Island, he also spends 24 hours living and working with its only human inhabitants - wildlife wardens Giselle Eagle and Richard Brown.

The actor 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.

Robson visits Essex and Suffolk for a journey along one of the most varied coastal landscapes in Britain, travelling 100-miles from the Thames Estuary in Essex to Southwold in Suffolk.
