view from an escalator going down in what appears to be a subway station. The escalator has chrome treads and the station has an arched ceiling with recessed lighting and rows of globe-shaped lamps on posts alongside the escalator. People are on the escalator ahead. An advertisement for auto mechanics is posted to the left, with a phone number and QR code displayed. The camera is held by a person on the escalator and someone's head and shoulder appears in the right side of the frame. A security camera is visible among the lamps.
