Kassandra "Kass" McQuillen

Three castaways face a game-changing decision minutes after the competition begins. Meanwhile, one tribe pours both blood and sweat into an early challenge and one castaway seeks revenge after discovering that her tribe wants to vote her out, on a special two-hour season premiere.

Twenty returning castaways are dropped in the middle of the South China Sea to begin their adventure. The new season in Cambodia, themed "Second Chance," features 20 castaways from past editions who were voted for by fans to have another shot at being named "Sole Survivor." For one tribe, old-school thinking battles new-school strategy when the two distinct groups try to take control of the game. Also, one contestant finds a clue to a hidden immunity idol that requires retrieving it in a way that's never been seen before.

The castaways' spirits are drenched by a monster monsoon. Meanwhile, two castaways form a "blue-blooded" alliance, and the "Brains" must win a challenge to avoid another trip to tribal council.

One Tribe considers throwing an immunity challenge in order to bench one of its strongest players. Also, a meltdown at a reward challenge could mark the end for one struggling castaway.

Castaways drop their buffs and form two new tribes. Meanwhile, a decision made on Day 1 could lead to a castaway's elimination and the battle for immunity proves which new tribe has the most Brawn.
