Meet the Circlemakers, a small group of artists predominantly residing in the South West of England who create jaw-dropping pieces of land art in crops every year.

But this is just the tip of the iceberg. And after multiple reports from Circlemakers about balls of light and other supernatural sightings, there is more to this story than meets the eye.
