Survivor: One World is the 24th season of the American CBS competitive reality television series Survivor , featuring 18 new castaways divided by gender into two tribes of nine. The cast is composed of 18 new players, initially divided into two tribes by gender: the 9 men composed Manono while the 9 women composed Salani. Notable cast members include Leif Manson, the first little person to compete on Survivor , and Monica Culpepper, wife of former NFL football player Brad Culpepper. The 18 castaways were divided into gender-based tribes and given maps to their camps, unaware they would lead to the same location. Despite living on the same beach, the tribes would remain split, building separate shelters and fending for their own tribe. As a result of the shared campsite, hidden immunity idols were designated for specific tribes; if a castaway found the idol designated for the opposing tribe, he or she was required to give it to a member of the other tribe before the next Tribal Council.

It's a battle of the sexes when tribes are separated into men versus women, but they are in dismay when they learn of a game-changing twist - they must share one beach. Meanwhile, castaways are shocked when a tribe's true colors are revealed at a competitive immunity challenge.

Castaways jump off the deep end in an Immunity Challenge that requires a delicate balance. Meanwhile, a group of misfits band together, finding an unlikely leader.

Weathering the harsh elements sparks new battles between the sexes, and poor communication leaves castaways scrambling at a frustration-filled Immunity Challenge.

An unforgiveable betrayal forces one tribe to make a drastic move that has never been done before in Survivor history, and an electrifying Tribal Council leaves several castaways speechless.

It's no longer men versus women when a new tribe of "Greek Gods" emerges, and two castaways shake up their entire tribe with an award-winning performance.

Extreme pain threatens to derail one castaway's chances of staying in the game and a conspiratorial Tribal Council once again shakes things up.

The game gets personal when one tribe member is confronted about her physical appearance, and a shocking blindside eradicates any sense of security in the Tikiano tribe.

Temptation is sweet for ravenous tribe members vying for individual immunity, and rumors of a hidden immunity idol send Tikiano into a tailspin as they head into Tribal Council.

Castaways go on the attack when one tribe member forces a confrontation, and a heartfelt message from home brings the Tikiano tribe to tears.

Castaways oil themselves up for a wet and wild immunity challenge. While the lucky winners enjoy a picnic vacation, Tikiano's sore losers strike at the chance to powwow at camp, and feelings of alienation drive leery tribe members to seek out all of their elimination options.

Walls come down when the Tikiano tribe shares an emotional moment with their loved ones, and one castaway's decision creates animosity amongst wounded tribe members.

An unlikely betrayal within an alliance puts one castaway on the defense, while another tribe member concocts an elaborate story to gain an advantage in the game.

For the first time, an all-women final five battle for the title of Sole Survivor, and one castaway breaks down before the final Tribal Council.

The winner is revealed as the 18 castaways reunite to discuss the season.
