The video is a nightvision recording of someone walking through some abandoned tunnels. After some walking he takes a turn and starts to go up some stairs, when Regan MacNeil runs up to the camera and roars, lightning flashing in front of her, then she vanishes and the person recording continues to go upstairs until the end of the video. However, the video is unavailable.
