The Elevator Goes Down Too Far

Wide shot inside a dim elevator, security camera angle (top corner). A man presses the lobby button, but the elevator stops at a floor labeled 'B3'—not on the panel. Doors open to a pitch-black hallway, a faint flickering light at the far end. He hits 'close,' but the doors stick. A single bare foot steps into the elevator, but no body follows. The man looks down—the foot is connected to a shadow that slithers across the floor. The elevator lights start to strobe, and the shadow rises to take the man’s shape. The doors close, and the elevator continues down. Style: clinical, cold, with a greenish tint, surveillance vibe.
