There is an old saying that "still water runs deep." The quiet little Southern town of La Flor, Mississippi, is an example of still water. While La Flor appears to be peaceful, placid, and lovely, underneath the calm is kidnapping, murder, and intrigue. One woman discovers the undercurrent of evil, but decides not disturb the peacefulness of the town's facade. When Sally Henshaw, a prominent La Flor attorney and Cornelia Connelly's best friend, mysteriously vanishes, residents of the sleepy town begin looking for someone to blame. Cornelia must take the investigation into her own hands to ensure that the real perpetrator is brought to justice - a quest that leads Cornelia into grave danger of her own. As she pieces together the puzzle of Sally's disappearance, Cornelia realizes that despite outward appearances, evil is everywhere.
