The video shows a first-person view walking through a tunnel or long hallway with an arched ceiling. The walls are brick on one side and concrete on the other, with arched windows above the concrete wall. Pipes run along the ceiling. The floor is concrete with arrows indicating the direction to walk. There are green glowing circles on the floor. A child in a white shirt and black shorts is walking ahead in the same direction. The lighting is dim, and the hallway appears to be underground.
