In the quiet town of Walnut Grove, something evil lurks within the occupants' minds. Only those dwelling twenty feet below Hattie's Bar and Grill are safe from the malevolent "holy water" handed out during Sunday church service. On the outside, the townsfolk are clean and friendly, but beneath the surface evil creeps toward an explosive and destructive end.

Ex-preacher Kirk David has come back to face his past and put to rest any lingering hope his sister might still be found after disappearing ten years ago. Once he arrives, he realizes God has sent him back for a more pressing reason. He must help a Cherokee Indian, Tom, find a stream blessed by an unknown prophet before a false preacher destroys the town.

Lenora Elayne dreams of a savior who comes on wings and thunder to help her save Walnut Grove from an evil man bent on destroying her precious town. God has given her charge over a pregnant teenager whose child will do great things in His name. All Lenora really wants to do is convince people that God loves them no matter what their sin, but her faith is shaky, and she fears she'll fail with the heavy burden placed upon her shoulders.

Together Kirk and Lenora find love and a renewed faith in God while trying to unravel seemingly unrelated events rushing toward a battle between darkness and light.
