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.
The year is 2047. Our planet is ruled by the repressive Confederate Central Government (CCG). Ryan is a Green War rebel agent sent on a mission by Sponge (Danny Glover) to collect evidence against the CCG for its heinous crimes. Ryan soon faces the sinister Colonel Asimov, Major Anderson and a group of mercenaries lead by Lobo. Ryan's mission quickly turns chaotic when he meets Tuage, a mutant survivor of the CCG rebellion who swears to help Ryan save what is left of their world - or does she?
