Une créature géante se manifeste dans la baie de Tokyo, avant de faire surface et de terroriser la ville. Le cabinet ministériel se réunit d'urgence, mais le Premier Ministre est incapable de prendre une décision. Les radiations mesurées sur le passage de la créature démontrent qu'elle est le triste produit d'une contamination. Plus tard, elle évolue et revient sous une forme encore plus monstrueuse, réduisant Tokyo en poussière.

Geologist Dr. Josh Keyes (Aaron Eckhart) and scientists Serge Leveque (Tchéky Karyo) and Conrad Zimsky (Stanley Tucci) become aware of an instability of Earth's magnetic field after a series of incidents across the globe. They determine that the Earth's molten core, which generates this field, has stopped rotating, and within a year the field will collapse exposing the planet's surface directly to devastating solar radiation. Backed by the U.S. Government, Keyes, Leveque, and Zimsky create a plan to bore down to the core and set off several nuclear explosions to restart the rotation. They gain help of rogue scientist Ed "Braz" Brazzelton (Delroy Lindo) who has devised a vessel made of "Unobtainium" that can withstand the heat and pressure within the Earth's crust and convert it to energy, as well as a laser-driven boring system that will allow them to quickly pass through the crust. Construction starts immediately on the Virgil, a multi-compartment vessel to be helmed by Space Shuttle pilots Commander Robert Iverson (Bruce Greenwood) and Major Rebecca "Beck" Childs (Hilary Swank) who will join Keyes and the others. To prevent a worldwide panic, Keyes enlists computer hacker Theodore Donald "Rat" Finch (DJ Qualls) to scour the Internet and eliminate all traces of the pending disaster or their plan.
