In this terrifying glimpse into the “American Dream” gone wrong, an unexplainable phenomenon has struck small-town Ogden Marsh. One by one, the townsfolk, who days ago lived quiet, peaceful lives are being reduced to depraved, blood-thirsty killers. While Sheriff Dutton (Timothy Olyphant) and his pregnant wife (Radha Mitchell) try to make sense of the escalating violence, the government uses deadly force to close off all access and won’t let anyone in or out, even the uninfected! An ordinary night becomes a horrifying struggle for the few remaining survivors as they do their best to get out of town alive.
