After Shang Lanxue dies, she inexplicably transmigrates into the wife of a county magistrate. She thinks she can spend the rest of her life in peace. But a bloody message on a handkerchief, severed limbs stuffed inside a corpse, a killer who skins their victims, and a concubine in the imperial palace who returns from the dead all drag her into a shocking conspiracy. As the plot unfolds, Shang Lanxue gradually discovers that her seemingly unremarkable county magistrate husband is hiding a terrifying secret.
