large crowd of people passing through turnstiles at what appears to be an indoor event or trade show. The crowd consists of men, women, and children of diverse ages, dressed in casual clothing. Above the crowd, a large black screen with a geometric pattern hangs from a metal structure. Spotlights are mounted on the same structure, illuminating the scene. An Audi advertisement is displayed on a large banner in the background. The environment suggests a modern, spacious building with multiple levels. The camera is positioned at an elevated angle.
