Геофизикът д-р Джош Кийс е направил ужасяващо откритие: вътрешното ядро на Земята е спряло да се върти. Това ще предизвика страховити природни катаклизми и ще промени живота на хората. Има само една надежда: Кийс и елитен отряд от учени да достигнат с подземен кораб до центъра на Земята. Съдбата на човечеството зависи от баланса и учените, заедно с корабния екипаж, трябва да направят немислимото - да взривят ядрени ракети, за да активират отново земното ядро.

When Earth's magnetic poles begin reversing, David Terran, the only scientist who predited the possibility of such a sci-fi disaster, must join forces with his estranged friend and lover to save the world. Though his writings found mass readership, scientists scoffed at his theories. But when an Iranian underground nuclear test sets off a global phenomenon that matches David's doomsday scenario, he must attempt to find a solution in order to avoid a catastrophic event of global proportions. -dpeavy

The Office of Scientific Investigations tracks down the source of increased magnetism and radioactivity in Los Angeles, and discovers that a man-made isotope is consuming available energy from nearby mass every few hours, doubling its size in the process. Although microscopic, it will soon become big enough to destroy Earth; and how to stop it is yet to be determined. The film's Deltatron special effects footage is taken from the 1934 German sci-fi film GOLD.

Near a small English village, a scientific team is conducting experiments with magnetic fields, the results of which may have military applications but the intensification of which seem to be connected to UFO reports, a series of murders, an enormous insect egg, and a strange visitor with exceptional scientific knowledge.
