This Sunday marks the fifth anniversary of Hurricane Katrina coming ashore. People who watched that storm said they’d never seen such violence in nature. Those who came back to New Orleans after the storm, would soon discover a kind of street violence that was well beyond anything the residents had ever seen. Helen Hill was a victim of a random killing in January 2007. She was a filmmaker, killed late one night in her home by an intruder. Her husband Paul and young son survived that night, but fled the city. Now Paul is making good on a promise, to finish Helen’s last film, an animated movie about an elderly woman from New Orleans named Florestine.
