In Nashville Mercy, a rising country music star mysteriously dies after undergoing a routine medical procedure. This catches the attention of the series’ namesake Kate Katelinson, an investigative reporter for the Nashville Herald, who becomes personally tied to the case and finds herself thrust into a twisted labyrinth of betrayal, corruption and murder after sources connected to her investigation start to die. Armed with only her investigative instincts and an unlikely alliance of friends, Kate enters a terrifying game of cat-and-mouse with a mastermind more powerful than she ever could have anticipated.
