The video shows a man wearing a hard hat and a light on his head as he walks through a tunnel. He is wearing a gray jacket and red pants. The tunnel is made of stone and has a wooden roof. The man is holding a flashlight in his hand and appears to be inspecting the tunnel. He is speaking to someone off-camera, possibly a colleague or a guide. The lighting in the tunnel is dim, and the man's light is the only source of illumination. The man's movements are cautious and deliberate as he navigates the tunnel.
