In the distant future, a large portion of humanity lives on Mars, in cities that resemble those once found on Earth. The cities are protected from the inhospitable Martian 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.
