Robert Fratta was a public safety officer in Missouri City, Texas, but is now facing the death penalty for organizing the murder of his ex-wife.

Filmmaker Werner Herzog explores a crime with no discernible motive. In 1996, two of Darlie Routier's young sons were brutally stabbed to death in Texas. Just seven months later, the once doting mother was convicted of murder and sentenced to death by lethal injection. Through compelling testimonies from investigators and Routier's family members, Herzog offers an unflinching look at this heinous crime.

On 24 August 1998, Douglas Feldman, then 40, was driving his Harley-Davidson in Plano when an 18-wheel truck passed him and suddenly pulled into his lane. Feldman then took out a 9mm pistol and fired several shots at the driver, killing him. Half an hour later, he drove into a gas station and shot another truck driver. Investigators could not establish a motive for the slayings. At his trial, Feldman testified that the first truck came so close that he feared for his life and became angry. While facing the death penalty, internationally renowned filmmaker Werner Herzog meets with Douglas to talk about his perspective on life and death.
