A man in a black sweater stands in a white hallway, gesturing with his right hand, while another person crouches behind him holding a dark coat; the crouching person then lifts the standing man onto their shoulders, causing him to fall backward and out of frame, after which the scene cuts to a man in a yellow and black jacket smiling and pointing, followed by a final shot of a person in a puffer jacket walking away from the camera down the hallway.
