The 30th season will feature the first-time theme of "Worlds Apart," with castaways divided into the three separate tribes, White Collar, Blue Collar and No Collar. Minutes into the game, castaways are forced to choose between honesty or deception, and one castaway becomes ill after trying to satisfy his need for protein.

White Collar castaways strip down and embrace their free-spirited "no collar" tendencies. Blue Collar castaways disagree when it comes to heavy lifting at camp, and one castaway struggles to adapt to her new tribemates.

In a "Survivor" first, the results of the fan vote for the 20 castaways who will compete in the fall edition will be revealed live by host and executive producer Jeff Probst during the live reunion show.
