"In Stonehenge Apocalypse, premiering Saturday, June 12, at 9PM (ET/PT), the ancient sandstone pillars of Stonehenge suddenly come to life, shifting along the earth’s power grid and creating devastating natural disasters around the world. Is Stonehenge really an alien terraforming machine, originally used to create a fertile, life-sustaining planet? And is its accidental re-activation going to destroy the earth? It is up to brilliant and eccentric radio show host Misha Collins (Supernatural) to prevent this by stopping a crazed cult leader (Hill Harper, CSI NY), eager for Armageddon. A production of Cinetel."
