The video shows a group of people walking through a tunnel. The tunnel is covered in fog, making it difficult to see. The people are walking slowly and carefully, trying to navigate through the fog. The fog is thick and covers the entire tunnel, making it hard to see any details. The people are wearing dark clothing, which blends in with the fog, making it even harder to see them. The video is shot from a distance, so the people appear small in the frame. The fog is moving slowly, and the people seem to be moving cautiously through it.
