Geological disasters get their own reckoning in this installment of the Desperate Hours series, moving past the obvious headline-grabbers like earthquakes and volcanoes to look at the slower, quieter killers. The film spends real time on the heat wave that scorched New Delhi in the middle of the 2010s, when two weeks of 45-degree temperatures got hot enough to melt asphalt on city roads. From there it moves through avalanches, landslides, sinkholes, and blizzards, using archival news footage, disaster imagery, and narration to build a case that these events cause their own share of misery even when the death tolls stay lower than a tsunami or a major quake. The structure is episodic, running through one hazard type after another rather than following a single event start to finish, but each segment sticks to concrete casualties, locations, and conditions rather than vague warnings. It is a survey film, built to leave you aware of how many ways the ground and the sky can turn on people.
