The image shows a group of people walking up and down a set of stairs in a large concrete structure. The stairs are made of concrete and have a metal railing on each side. The walls of the structure are painted in a light beige color and there is a green light shining down on the stairs. The people are wearing backpacks and carrying bags, suggesting that they are on their way to or from the top of the stairs to the bottom. The structure appears to be underground, as there are no other people visible in the image. The overall atmosphere of the image is dark and mysterious.
