In 1991, the murder of four teenage girls rocks the city of Austin, Texas. Amy Ayers (13), sisters Jennifer Harbison (17) and Sarah Harbison (15), and Eliza Thomas (17) were at the yogurt shop where Jennifer and Eliza worked, at closing time but never returned home. They were found later that night in the rubble of the store which had been set on fire. As the families grieve and the community comes together to find ways to heal, the police are thwarted in their investigations by a lack of hard evidence.
