Herzog’s very first film concept centered on a prison. Decades later, he reflects on a triple murder in a small Texas town through interviews with two men convicted of the killings. At the time of the murders, they were teenagers; now in their late twenties, one is on death row and the other is serving a life sentence. Herzog also has intimate, revealing conversations with prison and law officials, and family members of both the victims and the murderers, creating a complex portrait of the costs of death, whether at the hands of an individual or the state.
