The video shows a man wearing a cap and a light-colored sweater walking through a dark and narrow hallway. He is holding a flashlight in his right hand and a tablet in his left hand. The walls of the hallway are made of concrete and have some stains and holes. The man is walking towards a door at the end of the hallway. The door is open, and there is a staircase visible through it. The man then turns around and walks back towards the camera.
