The actor returns with another exploration of the rich history and culture of his home county, discovering some of Northumberland's best-kept secrets. In the first programme, GP and keen diver Ben Burville takes Robson out to one of the deepest parts of the North Sea in search of white-beaked dolphins. Next, he visits Cragside, once the country retreat of Victorian inventor Lord Armstrong and the first house in the world to be powered by hydroelectricity. Finally, Robson heads to Druridge Bay at sunrise to brave the chilly waters with a group of skinny-dippers.
