Ellie Harrison and Matt Baker are in the beautiful but little-known Clwydian range which spans Denbighshire and Flintshire in North Wales. Ellie discovers how this landscape influenced 18th-century artist Richard Wilson - said by many to be the father of British landscape painting. She also hooks up with the children of a local primary school where the pupils are turning a tidy profit by running their own chicken farm. Matt joins the conservation team cutting back the heather in the uplands and meets the brewer putting all those offcuts to good use in his heather-infused ale. Anita Rani spends the day with the sniffer dogs trained to sniff out not explosives or stolen cash but endangered animals, and Adam takes a look at how cutting-edge science is being used to create the perfect cow. From stealing priceless objects to stripping the lead from church roofs, heritage crime is a growing problem in the British countryside. Tom Heap investigates what is being done to protect our history.
