As he fights for survival, David knows he will be able to rely - as always - on his faithful sheepdogs Greg, Swift, Gail, Fern and Ernie. But even he is surprised when the dogs prove to be Borough Farm's secret weapon...A compelling portrait of a way of life that is as enviable as it is challenging.
