In this episode, passionate developer Rachel Ruffle puts forward plans for the Den Brook Windfarm. Its nine 120-metre-high turbines will transform the landscape in a valley just four miles from Dartmoor National Park. One of her allies is farmer Martin Tucker, who stands to gain hugely if the development goes ahead. Set against them are the local action group, claiming the turbines are visually intrusive and ineffective. And there is Mike Hulme, an increasingly disillusioned local resident who starts off on good terms with Rachel, but whose conscience is torn between the need for action on climate change, and his fears that turbine noise could blight the countryside's peace and tranquillity.
