See the planet as you've never been seen before as we challenge all of your preconceived notions about the world in which we live. Making use of cutting-edge scientific tools, this programme travels over, across and deep into the Earth's crust to learn just what makes your world tick. The result is a comprehensive portrait of a planet that defies your idea of terra firma, and instead lives, breathes and even flexes its muscles.
