At night, a group of people are arranged in a line performing synchronized movements. They are all wearing matching black athletic suits with red and gold trim, and white gloves. Most are moving their arms out to the sides, parallel to the ground. The setting is an urban street, with several multi-story buildings visible. Stores line the street, their signs illuminated. The camera appears to be moving slightly and is positioned at the end of the line of people.
