When Adams and his crew are sent to investigate the silence from a planet inhabited by scientists, he finds all but two have died. Dr. Morbius and his daughter Altaira have somehow survived a hideous monster which roams the planet. Unknown to Adams, Morbius has made a discovery, and has no intention of sharing it (or his daughter!) with anyone.
There will be a short (1/2 hour) film before the movie, a episode of "Fireball XL5": "The Forbidden Planet".
