Isle of Wight: Jewel of the South

In Yarmouth, upmarket hotelier Howard Spooner is preparing for one of the busiest weeks of the summer. He runs the exclusive George Hotel – which has been in business since the 17th century and even played host to King Charles II. Howard has a champagne client to impress and it's up to new recruit Maddie to keep their glasses topped up on the hotel's speedboat the "G-Dogg" without spilling a drop. In Briddlesford, fourth generation farmer and "Caulkhead" Paul Griffin is battling the summer drought. His 150-strong Guernsey herd produce premium dairy products for the island and beyond. Next year marks the centenary of the farm and Paul plans to mark the occasion with a new cheese – the "Briddlesford Red." He and his wife have arranged a cheese and wine evening for the island's discerning clientele. But will it be hit? In Ryde, entertainer Derek Sandy is preparing for his "Love Monday" entertainment night. Since arriving from Tobago 20 years back to escape a troubled past, he's taken the island by storm and become an institution. He's even written a song about the place. This week sees the final of his island wide talent competition – with hot favourites including a Dickensian rapper and a singer called Bubbles. In Bembridge, 74-year-old diver Martin Woodward shows us around the collection of items he's retrieved from the rich waters of the Solent. And Martin has just made the discovery of a lifetime. On a recent dive he discovered the long-lost cannons of the HMS Invincible – which sank in 1758. The cannons were jettisoned by the panicked crew in a vain attempt to save the ship, which sank soon after. Today, Martin will be heading back to check on their condition. And we follow Helen Butler on one of her regular forays into the island's verdant forests on her quest to save the 3000 native red squirrels. Being an island has kept the invasive grey squirrels at bay and Helen wants to keep it that way.
