A young woman returns home with her child to her ghost-haunted father, while a religious extremist hunts the stormridden territory of southern Mississippi to find the girl who may be a savior in the apocalypse. In the hurricane-ravaged bottomlands of South Mississippi, where stores are closing and jobs are few, a fierce zealot has gained a foothold, capitalizing on the vulnerability of a dwindling population and a burning need for hope. As she preaches and promises salvation from the light of the pulpit, in the shadows she sows the seeds of violence. Elsewhere, Jessie and her toddler, Jace, are on the run across the Mississippi/Louisiana line, in a resentful return to her childhood home and her desolate father. Holt, Jace's father, is missing and hunted by a brutish crowd, and an old man witnesses the wrong thing in the depths of night. In only a matter of days, all of their lives will collide, and be altered, in the maelstrom of the changing world.
