After the Snowfall

The town of Darrick, Illinois, is buried in snow, bringing it to a standstill. The next morning, as the residents try to dig themselves out, a strange thing is seen on the horizon. Three men, dressed in black, walk down the center of the only road in and out of town. Why do they instill fear in all who see them? What are their intentions? Who can help, when the world is buried in feet of snow?
