Matt and Anita explore the Isle of Wight. Matt dons a harness and abseils down the walls of Carisbrooke Castle to help root out the overgrown ivy. He then heads to the castle's well, the deepest on the island, to meet Jack and Jill - the Carisbrooke donkeys. Donkeys have been used to draw water from the well for centuries, but when Jack refuses to budge, Matt has no option but to do it himself.Anita has her hands full on Ventnor Downs. It's the day of the annual feral goat round-up, and Anita is joining the human chain of volunteers trying to catch the animals. She also visits the vineyard where the owner is growing red grapes - only possible because of the island's mild climate.That mild climate has also made the Isle of Wight a great place for exotic plants. Naomi is at Ventor Botanic Gardens, where the backdrop is more like southern Europe than southern England.Adam meets the commercial deer owner looking to genetics to breed the best deer he can and, as supermarkets and catering companies pledge to put an end to eggs from caged chickens, Tom Heap asks if this victory for animal welfare is all it's cracked up to be.
