This is basically a low-budget ripoff of the movie CORE. A crew piloting an experimental drilling machine accidently plows into some magma and sets off an earthquake, which starts to have a domino effect across the world. If they don't fix the problem then most of the earth's land masses will be destroyed. Since this first drilling machine was destroyed a second one is sent to do the job. It's crew is led by the Craig Scheffer (KILLER BUZZ) character, who is at odds with the funder of the project. Also on board are Terry Farrell (DEEP SPACE NINE, HELLRAISER 3), who looks really puzzled to be in such a cheap movie, and Will Wheaton, who really should have stuck with STAR TREK. Everything that happened in the movie CORE happens here but on a smaller scale, so if you've seen that movie then no sense seeing this one.
