Vesuvius buried Pompeii in AD 79, and this film follows the researchers using new tools to reread that catastrophe. X-ray scans of the plaster body casts reveal details about the victims' final postures and even bone structure hidden inside them for over a century. Satellite surveillance and 3D modeling map the volcano's current activity alongside the city's buried infrastructure, from water systems to street layouts, as archaeologists try to reconstruct how Pompeii actually functioned before it stopped functioning. The film moves between excavation sites, laboratories, and monitoring stations, with specialists explaining what each new scan or dig adds to a two-thousand-year-old puzzle. It also confronts the site's fragility directly: erosion, tourism, and funding shortfalls threaten ruins that survived the eruption itself, raising the question of how much more Pompeii can reveal before parts of it are lost. The result is less a rehash of the eruption story than a status report on how modern imaging is changing what historians thought they already knew about the city's last hours.
