A male-preserve for generations, one woman proves she has an eye for the stone and a knack for walling.

The North Yorkshire Moors are a mecca for artists from all over the world, but few are as lucky as John Freeman. Luke Casey pays him a visit at his studio in the port of Whitby, and follows him as he explains how he gets the inspiration for his work which is fast becoming collectors' items.

Running the Yorkshire Dales National Park is a potential minefield, but the new boss is determined to give it her best shot. Heather Hancock was a Whitehall high-flyer, working with three Home Secretaries before deciding to return to her Yorkshire roots and take on this challenging new job at the age of 32. Luke takes a stroll with Heather on her favourite Dales walk, high above the tourist honeypot of Grassington, and finds out what makes this remarkable woman tick in a job that has always been a male preserve.

Next stop Luke visits Masham to meet a remarkable couple who hail from the South East. John and Chris Clifton decided to move to Yorkshire when John retired from the Metropolitan Police. But retire is the last thing they've done; in fact, at the ages of 70 and 69 respectively, John and Chris are full-time dry-stone wallers - Master Wallers, indeed, an accolade that Chris received on the day of her 68th birthday.

Finally, to Arncliffe, Littondale where Luke finds Richard Paul a young Welsh farmer who moved into the area with his flock of Lleyn sheep seven years ago. Richard is now an established part of the community, and certainly the only farmer in the Dales who has to command his sheepdogs in two different languages.
