There are two supposed ghosts, if you can make them out. The second, which appears to be a young child, is the clearest, to my eyes. I took a still from the video and messed about with the picture but couldn't make the ghost appear any clearer or more distinct. But see what you think - the video is very short, less than one minute, and the actual ghosts are on screen for much less than this.
There is a 'Case File' of this particular Ghost Hunting Expedition on the Just Ghost web site.
