A secret nanotechnology experiment goes awry and results in a massive, deadly explosion. The company's CEO manages to sidestep blame by framing a meddling young reporter , who now holds the only surviving evidence needed to expose the truth. The the dangerous mini robotic nano particles-- having escaped from the explosion into the atmosphere-- threaten to destroy nearby cities with violent "death storms". As the storms intensify, and on the run from the authorities, the reporter- with the help of a young scientist-- races against time to get the evidence to the government and enlist their help to destroy the nanobots before they obliterate the planet.
