A sign warns "WATCH YOUR STEP" in a dimly lit corridor.
A low-angle view of a hanging white sign that says "WATCH YOUR STEP" in thin blue lettering, inside a corridor. The sign is a thin rectangular shape, and is a flat 2D paper, with two metal hooks on the top edge, to the left and right side. The ceiling moves from the foreground to background and is a slightly reflective material, with a dark gray color and dark lines moving across horizontally, from the left to right walls. Fluorescent lights are visible near the end of the hallway, to the bottom of the frame, and reflections of natural light are more clear at the end. The walls at the end are partially visible, but they have a tan color with metal frame panels.
