What would happen if a viral agent was released on American soil? How would local agencies react? How would the military respond? What if it was one of their own? Would they own it or attempt to cover it up? If a major operation was jeopardized because of the release, would that alter any of the decisions? A potent viral agent, created to destabilize a region for forces to move in and clean up, is accidentally spilled in a metropolis. Those infected serve only to afflict others through any means. As forces move in on the beleaguered city, Sergeant Brown has to make his way through roving bands of the infected in order to escape. Will the ring close before he can reach safe grounds or will he and others he finds be added to the final tally?
