It's not as fun as it sounds. What if, once a year, the government freed all in captivity for a day? Including prisoners, murderers, the mentally insane, etc. But, considering they're freeing everyone, Carnival Day is more like Carnival Week. If you get caught by one of the Freed, you become one. Some escape and never get caught again. But wait, what's that? Maybe there's hope, after all. A character just happened to come across what seems to be a rebellion sparking in western America. I wonder what will happen... (Seriously, though. I'm just making it up as I go.) ;)
