I found one of my favorite Twilight Zone episodes at You Tube. It's entitled "To See the Inivisible Man." It deals with a parallel universe where people are punished by one year's "invisibility" if they don't obey laws. If someone fails to shun an "invisible" they are also sentenced with invisibility. Sound familiar?
Here's more about the episode from Wikipedia:
Here are the You Tube videos (it's in 3 parts):
