A large group of men in black suits and hats dance in a circle on a wooden floor inside a spacious, well-lit hall with chandeliers, while a man in a black suit and hat stands with his back to the camera observing, and a young boy in a white jacket walks across the floor. The scene cuts to a man in a black suit and headphones singing into a microphone while playing a keyboard, then returns to the dancing men and the observing man as the boy walks past.
