The video shows a group of people walking through a dark tunnel. The tunnel is illuminated by a light at the end, which casts a glow on the walls and ceiling. The people are walking in a line, with one person leading the way and the others following behind. The walls of the tunnel are made of stone, and the floor appears to be made of dirt or gravel. The light at the end of the tunnel is bright, and it seems to be the only source of light in the tunnel. The people are moving slowly and carefully, as the tunnel is dark and the ground is uneven.
