David Koch (Jeff Fahey), a climatologist working for Miami-based Inter-Sci, is suddenly sent to Antarctica to investigate a change in climate. Some scientists on the icy continent were killed when there was an abrupt spike in temperature, resulting in shifting ice flows that sent them into the icy waters below. When David arrives down under, the remaining crew tell him that a "cave" has appeared, one that was not noticeable before, and which may have answers to the current phenomena. David leads a group to the cavern but, despite finding prehistoric "cave paintings" that suggest the climate on Antarctica was once warmer, the unstable weather creates death traps. Only David makes it out alive, natch. Back in Miami, David hooks up with a science colleague and his wife, Bryn (Erika Eleniak) who run data and come to the startling conclusion that the earth's "poles" are shifting and that Miami will become the new Antarctice in less than 4 days. Of course, the scummy, money-grubbing leader of Inter-Sci locks horns with David and insists to the United States military that the change in climate will evolve more slowly and that, in any case, the company has it covered. Ho ho, what fun is ahead! David, it turns out, is correct and soon folks sunning by the posh hotels' pools are being pelted with snow and sleet. With only a limited time to get everyone evacuated from Miami and into "warmer" New York and other upper regions, what will be the result? Actually, as far as "B" movies go, I thought this one was pretty entertaining. The cast is not stellar by any means, with Fahey and Eleniak, longtime B stars, looking older and tired and the others not doing Oscar work either. Then, too, the script veers off into silliness from time to time, as it tries to recount a long ago love affair between David and Bryn. But, when it gets down to science and special effects, the film fares much better. The whole premise is fairly interesting and the "chilling" of Miami is fun to watch. Yes, it takes a few pages from The Day After Tomorrow, with its rolling deep freeze frames. But, what the heck, if you love science fiction and chaotic weather situations, you would probably get a kick out of this one, especially on sweltering summer nights when re-runs are the only other options. Go for it.
