The video shows a dark, underground room with a pool of water in the center. The room is dimly lit, with the only source of light coming from a flashlight held by the person recording the video. The walls of the room are made of stone, and there is a small window on one side. The water in the pool is still and reflects the light from the flashlight. The person recording the video moves the flashlight around, illuminating different parts of the room and the pool.
