although the video box for many copy of this film claim it be about people turn inside out and this be a total lie . in fact and apart from the opening segment and the film isn not even a horror movie . with it sunken treasure and legion of fish people and and mad scientist and it a lot more like a doug mcclure adventure movie . obviously and this film be no work of art and but it kind of fun to watch . just be warn that the beginning be quite gory .
