Mallory Martin left her marriage and her unfulfilling job to move back to Arkansas and start a horse rescue. It's everything she's been missing, but when her cantankerous neighbour and longtime critic, Albert Cunningham, is found murdered, Mallory becomes suspect number one. Since Sheriff Grady Sullivan is ignoring all good sense and focusing only on Mallory, she decides to take matters into her own hands. Aided by her best friend, Lanie, and rescue volunteer Tanner, Mallory races headlong into the investigation in search of the real killer.
