What On Earth? Inside The Crop Circle Mystery

Intricate designs in crops turn up in farmers' fields overnight. Although they have appeared throughout the world for many years, no one knows where they come from or why they arrive. For twenty years, Suzanne Taylor has been part of a lively community of visionary artists, scientists, philosophers, geometers and farmers who are drawn to England by the circles every summer. This documentary tracks her interactions with these "croppies" as they go circle-chasing, indulge in circle-analysis, and share why they are so fascinated by the phenomenon.
