The rural town of Gatlin, in western Nebraska, is mostly run off by agricultural profits made from the vast cornfields surrounding the town. In one particular year, the corn crop fails due to drought and the people of Gatlin turn to prayer in an attempt to ensure a successful harvest. A mysterious boy preacher, Isaac Chroner, arrives and takes all the children of Gatlin into a cornfield to speak to them about the prophecies of a demon called "He Who Walks Behind The Rows". Isaac, through his lieutenant Malachai (Courtney Gains), leads the children of the town in a revolution, brutally killing all of the adults in the town with poison and sharp farm tools. A boy called Job has to witness it all.
