Stonehenge Apocalypse

When a disgraced scientist discovers unusual spikes in the Earth’s electromagnetic field emanating from Stonehenge, it is up to him to warn the world of a possible apocalypse. As his claims are disregarded by his peers, the ancient structure begins to move independently, build up an electromagnetic charge, and release enough energy to vaporize people within a certain radius. Can he convince the military and his peers of his findings before it is too late and all life on Earth is destroyed?
