Outside of a European castle a strange spacecraft lands. A being with a large weird head try to commnicate with a Robert Clarke and others in the castle. Is he friendly or maelevolent? William Shallart tries to exploit the being for his own personal reasons, turning him against the others in the castle. Very atmosphereic early Sci-Fi directed by Edgar Ulhmer. If there's such thing as a gothic science fiction film, this is it.
