Two field biologists from N.J. Fish & Wildlife discover a contagion being spread by a common marsh grass called Phragmites. Shortly after their reporting to the CDC, the contagion has found a human host, then another and another. In less than 24 hours, Phragmites will release their seed to the world, carrying the contagion with it. The event happens quickly and is known among those who study this grass as, November Seed.
