The video shows a first-person view of a person holding a gun and walking through a hallway. The person is wearing gloves and is holding a gun with a flashlight attached to it. The hallway is dimly lit, with only a few lights on the ceiling. The person moves forward, pointing the gun down the hallway, and then turns around and walks back the way they came. The walls of the hallway are made of concrete and there are no other people visible in the video.
