A large group of young children, presumably students at a school, are standing in a long line outdoors. They are uniformly dressed in white shirts and grey bottoms. Most of them wear sandals. An adult in a white coat and a red head covering stands amidst the children. Many of the children have their arms raised in the air. The background includes a brick wall and green trees. The ground is reddish-brown in color. At the beginning of the video, a loud sound like shouting occurs.
