Twenty castaways will compete in a tribal battle of the ages on SURVIVOR: NICARAGUA, when the Emmy Award-winning series premieres in its new Wednesday night slot. The 20 castaways will be divided into two Tribes of 10 when young battles old this season. The Espada Tribe, made up of individuals over the age of 40, must prove they have the life experience and knowledge that will ultimately help them Outwit and Outlast their younger competitors. The La Flor Tribe, consisting of individuals 30 years of age and younger, will have to use their youth and vitality to Outplay and ultimately Outlast their elders. Marooned in a land of smoldering volcanoes, savage wildlife and impenetrable terrain, the castaways will be forced to work together to adapt to their new surroundings, yet compete against each other to the stay in the game or be voted out by their peers. In the end, only one will remain to claim the million dollar Prize and title of "Sole Survivor." The show is hosted by Emmy Award-winner Jeff Probst.
