The twist is that the forbidden zone is not in a redneck, backwoods, and Deep South town during the rigid and violent Jim Crow segregation era. The bigger twist is that the Klan, Neo-Nazis, racist skinheads, and bikers didn't establish the racially restrictive zone. Purported Latino gang members established it. The forbidden zone is in a small, mixed ethnic bedroom community in Los Angeles. The year is 2007, not 1947.
