Iain Stewart tells the epic story of how the planet has shaped our history. With spectacular images, surprising stories and a compelling narrative, the series discovers the central role played in human history by four different planetary forces.

In this first episode, Iain explores the relationship between the deep Earth and the development of human civilisation. He visits an extraordinary crystal cave in Mexico, drops down a hole in the Iranian desert and crawls through seven-thousand-year-old tunnels in Israel.
