German volcanologist Tom Pfeiffer takes a group of volcano climbers on an adventure across the Danakil, and then on to the summit of Erte Ale volcano to see one of the world's few active lava lakes.
When Tom Pfeiffer hears that Anak appears to be going into a violent phase, he hops on a plane to Indonesia to see if the Child of Fire is ready to repeat the pattern of its ancestor.
