Series, based on Sheri Fink's book of the same name, explores the impact of Hurricane Katrina during the first five days after the storm hit in August 2005, and its impact on a local New Orleans hospital. The exhausted caregivers are forced to make life-and-death decisions amid rising water, intense heat and no power. These would haunt them for years to come. For example, the doctors were later accused of giving patients lethal injections so that they would die earlier.
