In the distant future, mankind lives on Mars, in cities that resemble those once found on Earth, protected from the alien atmosphere by dome-like force-fields. When a massive sandstorm breaks through the dome and destroys Mars New York, those in Mars Los Angeles must figure out how to stop the storm before it wipes them out next.

When a discredited L.A. Seismologist warns of an impending 12.7 earthquake, no one takes her seriously. Now on her own, she races desperately to get her family to safety before the earthquake breaks Los Angeles apart from the mainland.
