The action of the film is direct: Holt walks through the tall grasses of a swamp while filming with her Bolex camera, guided only by what she can see through the camera lens and by Smithson's verbal instructions. The viewer experiences the walk from Holt's point of view, seeing through her camera lens and hearing Smithson's spoken directions. Vision is obstructed and perception distorted as they stumble through the swamp grasses.
