On a sweltering July morning in rural Tennessee, fifty-year-old Rebecca Reynolds visits the family farm, where she literally stumbles across the mutilated bodies of her parents and younger sister, a sister who had spent life in a wheelchair after a birth fraught with complications. Rebecca's first thought is to call 911. Her second is to find her estranged sister, Lena, who was disowned by the family years before. Her third is to wonder how long it will be before Lena is arrested for the murder of their family. As the police gather evidence pointing to Lena, the sisters turn to attorney Brian Stone. Convinced of Lena's innocence, he agrees to take on the case. But in a family ripped apart by dysfunction, is anyone truly innocent?
