Jeff Davis, Texas, 1971. More than twenty people disappear in strange circumstances on a rural road known in the area by the name of Mountain Folks. The media has dubbed the case "The Mountain Folks Mystery."
Rosemary Morgan, a Black private detective from Los Angeles, decides to go to the area to investigate on her own. Initially, she will be following the trail of the last official missing person: Andy Sharpe, a friend of hers and an editor at the L.A. Times.
Near Mountain Folks is CookWard, the place of residence of most of the missing victims; a town whose inhabitants live, in many ways, as if they were trapped in the middle of the 19th century.
Once in CookWard, Rosemary will have to overcome countless obstacles, risks, and threats. To begin with, in the town, Mountain Folks will be a taboo subject that no one will want to hear about. On the other hand, the competent authorities of the county will refuse to collaborate with the detective. And, to make matters worse, the color of her skin will arouse a good dose of rejection among quite a few of the locals.
In an environment riddled with cowards and rogues, Detective Morgan will gradually delve into a case with no clues that will soon present her with a moral dilemma, and that will soon test more than just her many detective skills.
