A small fire burns with glowing embers, set on a concrete or tiled surface with a corrugated metal edge. Pieces of charred material, possibly wood or charcoal, are arranged around the burning section. A blurry, out-of-focus object of light-green color moves in and out of the frame near the fire. The environment appears to be an indoor or sheltered space with concrete walls. The focus is primarily on the fire and the movement of the green object.
