In 1995, one of the deadliest heat waves in the United States killed 739 people in Chicago. Why was the death count so high? And why were the deaths concentrated in poor, mostly African American neighborhoods? In her new documentary "Cooked: Survival by Zip Code," filmmaker Judith Helfand says it wasn't the heat that killed these people, but generations of institutional racism.
