A low-angle video shows three people walking away from the camera inside an indoor pedestrian walkway. The walkway is long, with shiny metal walls on either side, lit by fluorescent lights in the ceiling. Two adults walk in front, and a small child in a light-colored outfit runs ahead. The adults are wearing casual clothes and carrying bags. The walkway floor is black with a gray textured surface in the center. The end of the walkway has a door with vertical slats of some type.
