Synopsis
Experience an earthquake inside the San Andreas Fault, blast out of a volcano, encounter bizarre cave-dwelling creatures and enter caves full of giant crystals -- all inside our planet. As we descend we piece together our planet's extraordinary story, layer by layer, discovering how prehistoric forests became modern-day fuel, witnessing the dinosaurs' cataclysmic death, and watching as stalactites form and gold grows before our eyes. Deeper, beyond the reach of any mine, any drill, we find wonders beyond imagination: towering molten metal tornadoes, forests of solid iron crystals, until we reach the strangest, least understood place on the planet -- the core.
