John Craven is on Dartmoor, where he's exploring the working landscape both past and present. He joins the rangers restoring ancient leats - the old watercourses that powered mills, farms and tin mines - and meets the farmers carving out a living 'on the granite'. John also discovers a fascinating visual record of Dartmoor's farming community going back decades - photographer Chris Chapman has documented the highs and lows of farming life, from the beauty of newborn spring lambs to the horror of foot-and-mouth disease. And for the big finale, John meets respected local folk musician Jim Causley, whose music captures the spirit of the working landscape - especially his ode to the old mines, The Cry of the Tin. Also featuring highlights of the working landscape from previous episodes, including Anita Rani blowing up tonnes of rock in a quarry in Cornwall, Matt getting up close to a rare breed of working horse and Helen bouncing around in an underground amusement park
