The eighteen castaways, including Russell Hantz and "Boston" Rob Mariano, arrive in Nicaragua and learn that ousted players are sent to Redemption Island, where they live in exile and are given a chance to reenter the game if they can defeat other banished players in head-to-head competitions.

One castaway's kind gesture causes others to take notice and question his loyalty to the tribe, while Francesca settles into solitary life on Redemption Island and speculates who will join her next.

The last chance for immunity is a fight to the finish with an unlikely pairing of castaways, and the final three plead their case to the jury-find out who will outplay, outwit and outlast the others, on the two-hour season finale.

One tribe considers a risky move, while on Redemption Island it's do or die as Matt and Francesca face off in the first duel to see who earns the right to stay in the game and who exits for good.

Secrets are revealed on Redemption Island and the second duel reduces one castaway to tears when he is eliminated from the game for good.

Two unlikely castaways unite over their shared frustration with their tribe members while another castaway hides clues to keep their tribe from searching for the idol.
