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.

Castaways embark on the most grueling 39 days in Survivor history and test whether brute strength, looks or smarts will be the attribute that helps capture the title of Sole Survivor. Also, one castaway deals with excruciating pain when a bug gets stuck in their ear.

The merge brings another twist in the game that leaves two castaways out of the celebratory feast.

The remaining castaways fight for a game-changing reward to help determine their fate. Then, after 39 intense days of one of the toughest seasons in Survivor history, one castaway will be crowned Sole Survivor and awarded the $1 Million prize.

Survivors drop their buffs for a tribe swap, and the game starts from scratch for one set of castaways. Also, one castaway leaves his tribemates stranded in the ocean so he can search their camp for the immunity idol.

One castaway searches for an immunity idol they desperately need in order to stay in the game, and another castaway throws their game off balance after they lose their cool.
