All of a sudden the Earth's orbit begins to shift, causing cataclysmic changes in the weather. Scientists discover that, over time, the Earth's movement has been slowing to a halt. Ye gods! Geophysicist Dr Josh Keyes, and four 'terranauts', must journey to the centre of the earth and detonate a nuclear device to give the astral bauble that is planet Earth a much needed kick start.
Will they succeed? Real life geophysicist and editor of Ground Engineering magazine, Max Soudain, has seen the film. A man not easily pleased nor prone to spontaneous acts of superfluous approbation, Max described the movie as 'enjoyable hokum' and gave it a three out of five star rating. Praise indeed. Ground Engineering is sister publication to NCE, and a very attractive sister it is too.
