After 15 years and 30 seasons, the newest edition will feature the first-time theme of "Worlds Apart" with castaways from very different backgrounds divided into the three separate tribes. The all-new castaways will be grouped by White Collar, Blue Collar and No Collar. The White Collars (Masaya Tribe), known for making the rules, includes a corporate executive, a retail buyer and a marketing director. The Blue Collars (Escameca Tribe), known to follow the rules, consists of a postal worker, an oil driller and a contractor. The No Collars (Nagarote Tribe) boasts free spirits who are known to break the rules. This tribe consists of a coconut salesman, a sailing instructor and a YouTube sensation. These three tribes will have very different approaches to how they play the game and interact with each other, while sharing the same goal: to outwit, outplay, outlast and ultimately be crowned Sole Survivor and winner of the $1 million dollar prize. The show is hosted by Emmy Award winner Jeff Probst.
