At a secret aviation research station in the English countryside, an international group of scientists are working on the prototype of a revolutionary new aircraft, known as the M7, capable of flying at up to 2,000 miles per hour. The atmosphere is competitive rather than co-operative, with fierce rivalry between the various scientists. The project leader Michael Heathley (Donald) is so wrapped up with the M7 that his wife Lydia (Calvert) feels neglected and that she is being sidelined in favour of her husband's work. At a social gathering she strikes up a conversation with Heathley's colleague Alex Leon (Lom), and the pair are soon circling one another. Meanwhile, Heathley is desperate to test the M7, but is continually stonewalled by facility director Carrington (Maurice Denham).
The film is set in an unspecified time on Earth when the descendants of a genetically enhanced race created by mankind have control of the planet. Known as the "ghen" - a derivative of the word "generic" which humans labeled them as—the genetically superior race rule from their underground utopia, Hollow Earth. Baron Crecilius Pryme, a charismatic political from Ume City, sets out to convince his fellow ghen that what remains of the human race must be eradicated because he believes they are forming a crusade to attack the ghen. Crecilius shrewdly moves his brother, Aiden Pryme, into his deadly group of private soldiers known as "The Ministers", who hunt and abuse humans above ground.

The scientific team of Dr. David Conway (William Leslie), Dr. Ellis Morton (Tristram Coffin) and Laura Hutchinson (Kathryn Grant) has built a machine that can predict earthquakes. After predicting one will hit California within the next 24 hours to a uniformly skeptical Gov. Cheney (Raymond Greenleaf) and state-level political and civil defense officials, the earthquake does materialize and does immense damage to northern parts of the state. Now with the support and funding necessary from the reformed skeptics, the team works on further predictions and comes to the conclusion that a wave of earthquakes are pending in and around the southwestern United States. They trace the epicenter of the pending disaster to an area beneath the Carlsbad Caverns and descend to a hitherto unexplored level.
Trois parties se succèdent, avec les mêmes personnages, mais ayant des noms qui commencent par la même lettre. Chaque partie semble indépendante mais des indices, des apparitions issus de la partie suivante sont présentes dans chaque partie. Le personnage principal (Gary / Gavin / Gabriel) est toujours lié à Melissa. Ils sont d'abord acteur / attachée de presse, scénariste / actrice puis créateur de jeux vidéo / épouse. Melissa semble connaître la vérité sur ce qu'est réellement Gary, et une femme apparaît à chaque fois (sous le nom de S). S veut ramener G dans sa réalité en le forçant à oublier le monde qu'il a en fait créé (« Oblivio Acebit » : L'oubli arrive). Des symboles 9 apparaissent tout au long du film : un post-it « Chercher les neuf », il est impossible à Gary de tirer autre chose que 9 avec deux dés, il apparaît aussi sur les tatouages de Sierra sous la forme du chiffre romain IX.

Dr. Zorka, a rogue scientist, is the creator of various weapons of warfare, including a devisualizer belt which renders him invisible; an eight-foot tall slave robot (Ed Wolff), robot spiders that can destroy life or paralyse it and he also has a deadly meteorite fragment from which he extracts an element which can induce suspended animation in an entire army. Foreign spies, operating under the guise of a foreign language school, are trying to buy or mostly steal the meteorite element, while his former partner, Dr. Fred Mallory, miffed that Zorka will not turn his inventions over to the U.S. Government, blows the whistle on him to Captain Bob West of the Military Intelligence Department. Tired of answering the door and saying no to the spies and the government, Zorka moves his lab. When his beloved wife is killed, Zorka, puttering around for his own amusement up to this point, is crushed and swears eternal vengeance against anyone trying to use his creations to make himself world dictator. And would have if not for his assistant Monk, an escaped convict virtually enslaved by Zorka, who is cowardly, treacherous and totally incompetent, and whose accidental or deliberate interference with Zorka's efforts repeatedly frustrates his master's own plans.
