A young man in a yellow t-shirt stands in a dimly lit attic, reaching for a green bottle on a shelf, then turns and walks down a staircase into a well-lit hallway where a younger boy in a blue shirt runs past him into a bedroom, while another boy in a yellow shirt follows behind, and the first young man watches them from the top of the stairs before the younger boy returns and stands in front of him.
