Stretching from Indonesia's volcanic arc to the Himalayan peaks, this film follows the tectonic collision zone where the Indian and Eurasian plates have been grinding against each other for millions of years. It traces how that pressure builds the world's highest mountains while also feeding the eruptions and earthquakes that make the region so unpredictable. Geologists and field footage connect the dots between Indonesia's active volcanoes at one end of the zone and the slow, relentless uplift of the Himalayas at the other, showing how the same underlying forces produce both catastrophe and the planet's most dramatic landscape. The film moves across the zone's length, using satellite imagery, on-the-ground shots of fault lines and volcanic terrain, and expert explanation to lay out the mechanics of plate tectonics in practical terms. It treats mountain-building and volcanic destruction as two faces of one process, arguing that the same collision responsible for Everest's height is also responsible for the seismic risk faced by millions of people living along its length.
