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 reunite in Los Angeles to discuss the season. Jeff Probst hosts.

It's an epic showdown as two legends set their sights on one another. Also, two castaways attempt to put their past behind them and start a new game while another castaway introduces the "spy shack" 2.0.
