The video depicts a walkway or overpass filled with pedestrians. A woman in a green dress stands to the side near the railing, holding what appears to be books or papers. She has a blue plastic bag and a water bottle next to her. People are walking back and forth across the overpass. One person who is wearing a school uniform and backpack walks past the woman in the green dress. The structure of the overpass is metal, and there is a view of buildings and activity outside the overpass.
