DESCRIPTION: Our planet is bursting at the seams. Around the world, up to 30 volcanoes erupt every day - and hundreds more could explode at any moment. Meet the people and wildlife that live alongside these volcanoes from Kilauea to Mount Etna, and discover how volcanoes cause destruction but also create and nurture life. At the "burning heart" of this documentary is a daring expedition of scientists and adventurers to one of the world's most dangerous volcanoes alive today, located in the Pacific island nation of Vanuatu. Take a terrifying descent into the Marum Crater with biologist Jeffrey Marlow who risks a boiling lava lake to collect and analyze rock samples for signs of life. His discoveries could lead to a better understanding of the origins of life and a picture of what life might look like outside of Earth.
