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.

Six castaways battle it out for a shot in the final three, and a shocking tribal council delivers a Survivor first. Later, the final three castaways plead their cases for the $1 million prize.

Castaways' spirits are drowning in a relentless rain storm, but a fun challenge reward offers a few players a glimpse into the Cambodian culture. Also, the "voting block" strategy used this season continues to keep Castaways on their toes.

Castaways hover on the "Edge of Extinction" in an all-new twist, and four returning players attempt to bond with their new tribemates. Also, castaways tackle a giant puzzle in their first immunity challenge of the season.

One Tribe is completely puzzled at a classic immunity challenge. Also, one castaway attempts a heartfelt apology in an effort to stave off elimination before an intense tribal council.
