New York City, after decades of martial law, suffers a perpetual gray cloud cover and rainfall, a remnant effect the nuclear strikes upon the world's weather. Troops and armored personnel carriers patrol the streets. A curfew remains in effect.

That is until he is called to a grisly murder scene that appears to be an exact copy of a scene that January saw 10 years before.
