Matt and Ellie are in Somerset, where Matt is following in the footsteps of a legendary caver who first explored the caverns beneath the Mendips a century ago. He puts himself to the test squeezing and struggling through small dark spaces and finds that there's as much to Somerset below ground as there is above. Ellie tickles her taste buds with flavours of the sea as she visits the community-run project that's putting Porlock's once-famous oysters back on the culinary map. She also meets a man who makes furniture out of nothing but deer antlers. John discovers how a booming taste for cider is throwing our ancient orchards a lifeline, and he meets the scientist proving how important ancient orchards are for some of our rarest bee species. Meanwhile, Adam is on the Somerset coast helping round up the only 100% pure-bred herd of beef shorthorn in the country. Tom Heap investigates the growing demand for venison and asks whether we should be farming more deer in the UK
