When an offshore drilling platform in the Gulf erupts in flames and submerges, Antoinette Vitrini (played by Rachel Hunter), a brilliant and perceptive volcanologist, delves into the situation with astonishing findings. She verifies her hypothesis that a long-inactive subterranean volcano is present in the area and realizes that the unlawful deep-sea drilling has reawakened this dormant giant. Now, a massive flow of magma threatens to be unleashed directly beneath Miami. As Antoinette and her team work to avert the looming catastrophe, they must also confront the corrupt corporation responsible for the crisis.
