We've Sensed It. We've Seen The Signs. Now... It's Happening.
Philadelphia high school science teacher Elliot Moore and other people begin encountering breakdowns in human behavior in major American cities that lead to chilling deaths that seem to be willing suicides committed by the victims.
The victims undergo a series of steps: loss of speech, followed by disorientation, and the third step is "fatal." Moore flees from the crisis into Pennsylvania farmlands with his estranged wife Alma, math teacher friend Julian, and his daughter Jess.
