A man is found dead in his rural Mississippi home, shot four times with his own 9mm pistol. His 19-year-old son names his hospitalized mother, Michelle Byrom, as the mastermind of the murder, claiming she hired the boy's friend to shoot her husband, and promising to pay him from the life insurance payout. Sentenced to death, Michelle spends 14 years awaiting execution - until a determined team of lawyers unearths a dark history of domestic and sexual violence, and a confession that points to an alternate suspect.
