In Chicago in 1931, Asta Eicher, a lonely mother of three, is desperate for money after the sudden death of her husband. She begins to receive seductive letters from a chivalrous, elegant man named Harry Powers, who promises to cherish and protect her, ultimately to marry her and to care for her and her children. Weeks later, Asta and her three children are dead.
Emily Thornhill, one of the few women journalists in the Chicago press, wants to understand what happened to this beautiful family, particularly to the youngest child, Annabel, an enchanting girl with a precocious imagination and sense of magic. Determined, Emily travels to West Virginia to cover the murder trial and to investigate the story herself, accompanied by a charming and unconventional photographer equally drawn to the case. These heroic characters, driven by secrets of their own, will stop at nothing to ensure Powers is convicted.
