In her artistic practice filmmaker Katja Verheul questions what remains after a war, and what the impact of these remains is on people and nature. Red Dust is a haunting visualisation of sand dust from the Sahara that, while passing through France, turns the sky red. This dust is a time capsule containing cesium-137 from the French nuclear tests in Algeria. Researching this natural phenomenon, Verheul exposes what lasts of a war that was never fought.
