A daring weather experiment unleashes a devastating onslaught of freezing windstorms and lethal ice tornadoes throughout the Pacific Northwest. The region locked in the arid grip of a debilitating drought, scientists and experts attempt to instigate precipitation by launching liquid-condensing drones into the clouds. When the drones experience an unexpected error, however, a storm begins to brew. The freezing winds quickly gaining momentum, there appears to be no way of calming Mother Nature's fury. Before long, the deadly gusts have formed massive, frigid twisters, sending the frightened populace running for cover. With precious little time to spare, it's now up to the very same people who created this freak storm to put it out of commission before it can reach the big city.
