A video shows a series of children walking on a sidewalk in a residential area, seemingly on their way to or from school. The first clip shows a teenager carrying a younger child piggyback down the sidewalk. Then, it cuts to a group of older children wearing backpacks walking in the opposite direction. There's a car parked nearby, and a school building in the background. The scene then returns to the teenager carrying the younger child. The setting appears to be a bright, sunny day.
