A video shows a group of people, most of whom appear to be children, walking across a green artificial turf field marked with white lines. The group is walking from left to right in the frame. They are wearing various colored shirts, including yellow, purple, orange, and white. Some are also wearing blazers. Several carry banners, including one that says "AMETHYST HOUSE." A large white tent is visible in the background, along with a building with a gray exterior. The sky is overcast. There is music playing in the background.
