The coastal adventure continues as Helen, Jules and JB explore the wild shorelines of Cumbria, Aberdeenshire and Suffolk, uncovering stories of smuggling, seafaring and surprising seafood.

In South-West Scotland, Helen heads off-road into the rolling hills of Bainloch Deer Park, home to over 600 Red, Sika and Fallow Deer. Alongside park manager Richard, she sets out in a 4x4 to get up close to the herd and discover how this enclosed sanctuary offers a vital refuge from modern threats. Then it's time to take to the water - Helen grabs a paddle and joins the Kirkcudbright Kayak Club to uncover the region's colourful history of 18th-century smuggling. With taxes sky-high on goods like tea and tobacco, cunning traders turned to the Isle of Man for cheaper contraband and launched secret coastal trades that helped fuel the local economy.

Further north, Jules explores the dark history of HMP Peterhead - Scotland's own Alcatraz. Built by convicts using locally quarried granite, the prison housed some of the country's toughest criminals. Now a museum, Jules explores its past with a present-day officer. Then, in Johnshaven, he finds a tastier tale: lobster, once a "poor man's food", is making a local comeback thanks to a community-led lobster shop and café reconnecting residents with their seafood roots.

On the Suffolk coast, JB gets hands-on with a spectacular reconstruction of the Sutton Hoo ship. He joins a team of volunteers' hand-building a full-size replica of the legendary Anglo-Saxon burial vessel using ancient tools and techniques. Finally, he fast-forwards to the present with a crash course in wing foiling at Felixstowe. Balancing on a hydrofoil while harnessing the wind, JB attempts to fly above the water's surface - gracefully or not!

And as always, the team share updates, banter and a bit of coastal competition from three very different corners of the UK.

JB Gill explores the Sussex coast in Brighton, home to beach huts, saunas and the i360 - Europe's tallest moving observation tower. In Merseyside, Helen Skelton joins the crew of the RNLI's high-speed Shannon lifeboat. Jules Hudson visits the Portsmouth Historic Dockyard on the Dorset coast, uncovering a personal chapter of naval history and tracing the story of his great-uncle George Norcott.
