Mount Vesuvius erupted in 79 AD and buried Pompeii under ash and pumice, freezing the Roman city in place for nearly two thousand years. This film follows the scientists and archaeologists now applying laser scanning, 3D modeling, and DNA analysis to that frozen snapshot, reconstructing streets, buildings, and the bodies caught mid-flight in the eruption with a level of detail earlier excavations could not reach. The DNA work in particular lets researchers speak to who these people actually were, rather than just how they died. Alongside the reconstruction work, the film turns to the mountain itself, still classed as one of the most active volcanoes in the world, and asks what current monitoring shows about the odds of another eruption. It also tracks the pressures on the site today, from the wear of heavy tourism to the risk of landslides, both threatening a city that survived the volcano only to face slower kinds of damage now. The two threads, ancient catastrophe and present-day risk, run side by side throughout.
