Charlie Cooper's odyssey takes him to Wiltshire, home to ancient sites such as Stonehenge, Avebury and the Westbury chalk horse. He wants to get to the bottom of why humans feel the need to leave marks on the landscape.He soon turns his investigation towards a far more recent phenomenon, crop circles, hoping to settle a debate that has plagued his family for years. They believe that crop circles are the work of aliens, but Charlie strongly doubts that. He meets with farmers and secretive 'croppies' (humans who create crop circles), trying to find out how these vast and intricate shapes appear overnight.Helped by his friend Scott, Charlie takes his research one step further and attempts to shed light on the phenomenon by making his very own crop circle. The humorous trip aboard an old AA van shows him that you only need to scratch the surface anywhere in this land to discover that folklore, myth and legend are very much alive and exert a beguiling power.
