One of those Lucio Fulci films where the plot is none of the viewers business! Thrill as people mysteriously die in over the top ways as we do not have an inkling as to how are why! Panic as the main girl seems to be doomed, for some reason or another and wrinkle your head in confusions as the credits roll and you still cannot fathom what you have seen!
