Based on true events, six investigators head to one of the world's most haunted places to uncover the source of supernatural sightings and phenomena. Known for centuries as a notorious magnet for grave robbers, body snatchers, Satanists and cultists since the time of The Black Death, the ruined St. Mary's Church at Clophill plays host to filmmaker Kevin Gates and his team of researchers. Obsessed with unraveling the secrets of this "unholy ground," they venture into the murky darkness armed with cameras, curiosity and a need to expose the truth. However, some secrets were meant to stay buried -- permanently. Over the course of three chilling nights, it becomes clear that they have unleashed something ancient and evil that has long been hungry to escape into this world.
In March 1963, a black mass was held at a ruined church in Clophill, Bedfordshire by a coven of dark witches. Tombs were looted, animals sacrificed and human bones arranged during a macabre ceremony. Further defilements continued at Clophill in the following years, with cattle in nearby fields found mutilated, evidence of necromancy discovered and perpetual sightings of paranormal activity witnessed at the isolated ruin. 50 years on from the original incident, the Clophill legend remains etched on the psyches of the local populace. In 2010, a documentary team was assembled to investigate the legend of the Clophill witches and to try and uncover the truth behind the paranormal events. What followed during that long weekend at Clophill was a terrifying journey into the unknown.
