FINALLY!!! From the press release:

Survivor, the Emmy Award-winning adventure reality program, returns for its 24th series when Survivor: One World premieres Tuesday, May 15, at 10.00pm on Channel Nine.

Hosted by Jeff Probst, Survivor: One World pushes the game of survival to its limits, forcing two competing tribes to share one beach.
Eighteen castaways must fight the elements, adapt to their new surroundings and vie against each other to stay in the game or be voted out by their peers, all while living together on the same beach. The tribes, divided into men versus women, will have to decide whether to share their resources with each other, or leave the opposing tribe to fend for themselves.

The ultimate test of survival strategy becomes even more difficult to navigate because alliances could be formed between members of different tribes much earlier, adding another layer of intrigue to this ultra-competitive game. The castaways will be divided into two tribes of nine: the Salani Tribe and the Manono Tribe, named after islands in Samoa. The tribes are comprised of individuals from different backgrounds with the same ultimate goal: to outwit, outplay, outlast – and ultimately be crowned the Sole Survivor.
