Palau

Twenty people are stranded on a group of islands in a remote part of the Pacific, competing for a $1 million prize.

Koror discovers their beach is infested with rats; romance brews at both camp, which leads to suspicion all around.

Jeff suffers an injury that may cost his tribe a challenge; a lack of work ethic within a team disturbs one of its members.

Tensions arise when both tribes must choose a leader for a reward challenge; one group considers banding together against another tribe member.

One tribe gets lost looking for new shelter during a storm; one tribe has to watch the other enjoy a reward.

The seventh castaway is voted off; a night spent enduring a typhoon-force storm causes one castaway to break down emotionally and physically.

Tom goes head-to-head with a shark; when one tribe member is forced to sit out a challenge, the other members begin to doubt the tribe's ability to win.

Stephanie becomes increasingly irritated at Bobby Jon's behaviour; the castaways sample a Palauan delicacy that is hard to swallow.

Stephanie becomes the last member of the Ulong tribe and must survive on her own; some of the castaways enjoy a memorable evening, and one indulges a bit too much.

The first to quit the immunity challenge is banished to another island; when one castaway confronts the tribe, everyone is left feeling uncomfortable and that castaway feels alienated.

Certain tribe members work to form a secret alliance; one castaway follows advice and makes improvements to personal hygiene; three contestants devise strategies to survive the upcoming tribal council.

Some castaways are reunited with loved ones; a strong alliance alienates one castaway, for whom immunity is the only chance for survival.

Alliances are further splintered as each castaway feels the pressure to make it into the final four; one contestant feels betrayed when the winner of the reward challenge chooses someone else to enjoy the reward.

The contestants gather for one last time as the jury casts their votes for they believe should win the competition.

The 20 castaways reunite for the first time since the the beginning of their adventure and reflect on their experiences together.
