A crew of thieves plans the ultimate heist, to steal $600 million from the U.S. treasury facility located on the Gulf Coast of Alabama using a hurricane as their cover. When the storm blows up into a lethal Category 5 and their well-made plans go awry, they find themselves needing a vault code known only by one female Treasury Agent, a need that turns murderous. But the Treasury agent has picked up an unlikely ally, a meteorologist terrified of hurricanes but determined to save his estranged brother kidnapped by the thieves. He uses his knowledge of the storm as a weapon to defeat the bad guys.
