A close-up of a rusty chain attached to a train car transitions to a model train, a green engine with a face, pulling a line of freight cars along tracks through a model railway yard with buildings and cranes. The scene then cuts to a man with glasses and a beard, wearing a black shirt, who is sitting on a white couch with a purple blanket, looking directly at the camera with a wide-eyed, open-mouthed expression of shock or surprise.
