Images of sixteen men and women are shown, one by one, as they run on a conveyor belt against a black background. They appear to be in a complete void. The camera films the runners from all kinds of angles: sometimes from the front, from the knees up, then in profile or a focus on one of the limbs in close up. The heavy breathing of their exertions is audible. The tight close-ups of the limbs lend the moving body parts an almost abstract, mechanical character.
