At it worst, the Spanish Flu of 1918 killed four times as many people as the Black Death. The Alaskan village of Brevig Mission, site of a deadly outbreak eighty years earlier, is home to the U.S. government's lab assigned to research a vaccine. When evidence reveals that a Saudi extremist cell has chosen the flu virus as the next major biological weapon, the government must protect the lab at all costs-and a civilian security company is assigned to test the facility's defenses. When the SecurityCheck team discovers that the flu has been released, they must fight the clock to stop the threat-and find a cure.
