Werner Herzog reunites with volcanologist Clive Oppenheimer—met on the shooting of Encounters at the End of the World—for a scientific and metaphysical quest as close as possible to volcanoes, from the Vanuatu archipelago and Indonesia, to Iceland, via Ethiopia and North Korea. Over 30 years after having filmed a volcano for the first time (La Soufrière, 1977), Into the Inferno witnesses Herzog's look at the hypnotising beauty of the craters in fusion but also at those who live near volcanoes. Throughout this exploration across the planet and the ages, strange links between volcanic phenomena and history, all kinds of myths and cults, are weaved together. Through passionate meanderings that lead us as much in search for early men bone fragments, as they do into the heart of the North Korean propaganda machine, or to a ceremony to the glory of G.I John Frum, the film finds its unity in these thought systems born in the shadow of the volcanoes. Lying somewhere between a tale about the origins and the announced end of the world, it captures what bonds men to each other.
