After surviving the brutal stabbing that leaves her two sons dead in 1996, Dallas housewife Darlie Routier urges police to find the intruder she claims is the killer. To her horror, she becomes the No. 1 suspect. In his first interview in nearly 15 years, Darlie's husband, Darin Routier, gives an emotional telling of the events leading up to her arrest while the prosecutors, Greg Davis and Toby Shook, walk through the crime scene as they prepare their case.
Amid a media frenzy, Darlie Routier's trial begins in the small, conservative town of Kerrville, Texas. Prosecutors know they will be up against a formidable adversary when Darlie's family hires one of Dallas' top attorneys, Doug Mulder. For the first time in the series, we hear from Darlie on death row and her first-hand account of what happened that night, an account investigators say was 100% fabricated after Darlie staged the crime scene. The state's investigators will present its evidence pointing to Darlie as the killer, but 20 years later, defense experts examine their theories, one by one.
