Here is a synopsis from the official site:
Two years after Katrina, parts of the city are still in chaos, but hope has emerged. Battling an upsurge of violence, understaffing of police forces and a lack of crime labs and other facilities, the cops who remain in the New Orleans Police Department have courage to burn and a passion to reclaim and rebuild their city.
Check out the Fox main site (http://www.fox.com/kville/) as well as IGN.com, AOL.com, Yahoo, and TVGuide.com for access to the first episode.
This show has the potential to tell a side of life in post-katrina New Orleans that a lot of people dont realize. Here's to hoping that they show what's really going on out there instead of merely using New Orleans as a backdrop for the same old cop dramas we've seen before.
