Iceland sits directly over a geothermal furnace, and this film opens in its steam fields, tracking the forces that keep glaciers capping active supervolcanoes like Katla. Geologists explain how the island itself is being pulled apart along the Mid-Atlantic Ridge, feeding the eruptions and hot springs that define its landscape. The film then follows the same tectonic story west and south to the Alps, where Africa's slow collision with Europe has been crumpling the crust for tens of millions of years, throwing up peaks that are still rising today. Footage moves between crater lakes, ice caps, and mountain ranges, with scientists on location describing how plate movement, volcanism, and glaciation interact across the wider Eurasian plate. The film treats Iceland and the Alps as two visible chapters of one continental process, using field interviews and landscape photography rather than reenactment to make the geology legible. It closes on the same point it opens with: this ground is still moving, and both landscapes are evidence of forces still active underfoot.
