Under dirty black skies, the town of Dead Crow is deluged by days of rain, flooding the streets and cutting it off from the outside world. Chief Andy Curran already has his hands full, getting residents to safety and battling a greedy mayor. But now people are going missing in the endless rain.
Curran soon discovers that there are things living in the overspilling river that threatens to drown Dead Crow. Their eerie clicking sounds drift across the frightened town as they emerge from its toxic waters. The rain isn't stopping. The clicking is getting louder. And the screams are only just beginning.
