Matt Baker and Margherita Taylor are in a very snowy Devon. Matt looks at the work of photographer James Ravilious, who spent years photographing the Devon countryside. He meets Brian Low, one of the farmers who appeared in the photos back in the 1970s and discovers what Ravilious's legacy means to him. Later, Matt returns to Brian's farm to meet some just-born calves, before heading to the farm of Lisa Lucas Ridge, where lambing is in full swing. Margherita meets the people from the Axewood Co-operative, a group who chop down wood and give it away. Margherita meets some of the beneficiaries of this log bank and finds out how this initiative is helping ease fuel poverty locally. Margherita also heads to Greenway, the fabled summer home of Agatha Christie and inspiration for many scenes in her books. The gardens are famous for their camellias, which are in full bloom despite the icy weather. Also in this programme, Hannah Cockroft does a spot of bird-watching, Tom Heap investigates the growth of illegal bloodsports online and Adam Henson sees how virtual reality is being used to train the farmers of the future.
