Five Days at Memorial recalls the real and horrifying events that went on at a New Orleans hospital during the aftermath of Hurricane Katrina. Over the course of five days, the caregivers in charge try their best to evacuate thousands of people from the building, but heavy floods, power outages, intense heat, and a sorry lack of planning result in some heartbreaking decisions about the fate of their patients.

The ongoing series is a gut-wrenching and at times excruciating watch, adeptly directed by John Ridley (American Crime) and absorbingly moored by a cast that includes Vera Farmiga (Conjuring)—by now an expert at exhibiting pure horror—and Cherry Jones (Succession).
