The film tells the story of the creation of the first hydroelectric power stations in Morocco — Flilou and Sidi Saïd — which were built by the French company Penarroya to supply electricity to the Ahouli mines. The goal was to facilitate drilling operations for the extraction of lead ore. It also highlights the village of Tattiwine, located about 12 kilometers from Midelt, which served as the main water source for the Flilou station. Additionally, it covers the Sidi Saïd power station, which was supplied with water by a nearby dam to generate electricity.
