A man in a dark uniform stands in a narrow hallway, then the scene cuts to two individuals in light-colored uniforms looking forward. The view shifts to a long, white corridor where a group of people in dark uniforms are running toward the camera. As they approach, they begin to fall backward in a synchronized, cascading motion, tumbling down the hallway in a chain reaction until they all collapse on the floor. The setting is a stark, brightly lit corridor with white walls.
