Matt Baker and Helen Skelton are in Derbyshire where Matt is exploring the boom in farming alpacas. He meets Ingrid Rushton, one of the first people in the UK to own them and visits a blood transfusion drop-in for alpacas where owners have come from all over the region bringing their animals to donate blood which could save baby alpaca's lives. Helen tries her hand at 'weaselling', the latest craze to sweep the Peaks. It's a kind of potholing that happens above ground and joins a party of schoolchildren who squeeze in and out of the rocky tors that dot the landscape. She also meets countryside champion Yvonne Witter who has made it her mission to get more people from ethnic backgrounds into our countryside. Tom Heap looks at illegal abattoirs and asks if the meat on our plates is what we think it is, and Adam is in North Wales meeting the farmer using a special type of working dog to manage his livestock.

Steve Brown is on the trail of an elusive and endangered Scottish creature - the mud snail. They may not be one of nature's glamour species, but these tiny molluscs play an important role in the ecosystem. Anita Rani cycles along the sands of the East Lothian coast on a 'fat bike'. With larger than normal tyres they leave virtually no trace in the sand, having as little impact on the natural habitat as possible. Matt Baker visits St Abbs - a community who refused to let their lifeboat service go under. When threatened with closure they independently took on the community lifeboat, saving 104 years of history. There are ten million cattle farmed in the UK, and it is a well-known fact that livestock like cows produce a lot of methane, which contributes to global warming. Adam Henson is in Edinburgh at an agricultural college where they are working on a solution. Tom Heap looks at companies buying up swathes of countryside and selling it on with planning permission for houses.
