What keeps the surface of the Earth in perpetual motion? The movement of the Earth's plates provides scientists with a really challenging question – what is the driving force? In search of the answer, this programme visits - the world's most active volcano, Mount Kilauea in Hawaii; Iceland,the largest volcanic island on the planet, which seems to be splitting in two; Sweden, to see the work of scientists who are probing the secrets at the Earth's very core; and to the Kanheri Caves in Western India, which provide striking evidence of violent events deep inside the planet. Hidden beneath people's feet is a surprisingly complex and changeable world, where matter exists in forms never seen at the surface, and huge plumes of hot rock periodically rise through the Earth to erupt at the surface with devastating effects. Beneath our feet is the vast, churning heat engine of the Earth's interior, which drives the dance of plate tectonics, reshaping the surface of our world and changing the course of evolution.
