Journalist Bram Vermeulen crosses the Sahara from the Atlantic coast of Mauritania to the Red Sea, tracing a route that colonial powers mostly left alone because the terrain was too hot and too vast to control. Three episodes follow his path through Mauritania, Timbuktu, and Niger, and the film treats the desert as a political frontier rather than empty space: Europe now funds border posts and anti-terror patrols here to stop migration before it reaches the Mediterranean. Vermeulen talks with Tuareg guides, migrants stranded mid-journey, and people living under systems of hereditary slavery still functioning in Mauritania, and he tracks how jihadist groups have moved into the power vacuum left by weak states. Human traffickers, smugglers, and local officials all get camera time, giving the series a reported, on-the-ground feel rather than a scenic travelogue. Heat, sandstorms, and long stretches of empty road are part of the texture, but the real subject is who controls this space now and what that costs the people who call it home.
