Back in the 1980s, three southern sisters return to their hometown of Furriston, Mississippi after their mother dies of a brain tumor. As the oldest sister, Margaret, tries to settle the affairs of her mother’s agriculture business, the middle sister, Penny, seduces and slays an out-of-town rapist that preyed on her best friend, Amanda. Unbeknownst to Penny though is that the murdered man’s brother, Barden, is a leader of a meth gang. And now Barden and his Boar gang are turning over every stone in Furriston, looking to get revenge on whoever killed his brother.
But Margaret, Penny, and even their little sister Annie have been harboring a dark secret from the rest of the town. They are serial killers, pathological murders that were trained by their father since they were girls to stalk, slaughter, and disappear. A full-blown gang war is about to erupt in the small rural town, and it’s about to bring out the good, the bad, and the evil in human nature.
