Rain Bomb explores the terrifying phenomenon of downbursts—violent, fast-forming storms that strike without warning and leave devastation in their wake.

From a £14 million superyacht sunk off the coast of Sicily to explosive winds flattening vast swathes of the Amazon rainforest, the film reveals how climate change is making these events more frequent and more dangerous. With exclusive access to cutting-edge research, the documentary follows French and international scientists as they deploy drones, lidar mapping, and wind-tunnel testing to decode the growing power of rain bombs—and uncover how communities might be protected from their destructive force.
