When a group of archaeologists dig up a human skeleton near Stonehenge, an ancient piece of machinery hidden beneath the bedrock is discovered. Not knowing what it could be, the workers accidentally trigger the mechanism and start a chain of events that may very well end the world as we know it

Stonehenge is an icon of prehistoric British culture, an enigma that has seduced archaeologists and tourists for centuries. Why is it here? What is its significance? And which forces inspired its creators? Now a group of international archaeologists led by the University of Birmingham and the Ludwig Boltzman Institute in Vienna believe that a new state-of-the-art approach is the key to unlocking Stonehenge's secrets. For four years the team have surveyed and mapped every monument, both visible and invisible, across ten square kilometres of the sacred landscape to create the most complete digital picture of Stonehenge and the surrounding area over millennia. Operation Stonehenge takes the viewer on a prehistoric journey from 8000BC to 2500BC as the scientists uncover the very origins of Stonehenge, learning why this landscape is sacred, preserved and has been revered by following generations.

Spinal Tap, having put Stonehenge on the map in their legendary song about the world heritage site, pay their first visit to the monument. As if drawn by some primal, magnetic force, Nigel Tufnel, David St. Hubbins and Derek Smalls set out on a pilgrimage to this ancient site. The silent song of these mysterious lithic Sirens inspires the distinguished artistes to make a trans-generational house-call.

Shot at Stonehenge, the mysterious landmark that we now know must have been erected thousands of years ago purely to serve as the setting for the last act of Spinal Tap. The ultimate meeting of rock mythology and cinematic scale. An iconic band performing at one of the world’s most legendary landmarks and turned up to eleven.
