The three tribes learn that two teams will be attending tribal council as one combined unit to send one castaway home, when they participate in a classic immunity challenge that sends players flying blind.
The castaways drop their buffs for a tribe swap and the game starts from scratch for one set of players. Later, one castaway leaves his tribemates stranded in the ocean so he can search their camp for the immunity idol.
Twenty of the game's biggest competitors return to play as the reality series begins its 34th season. In the opener, the castaways arrive at Fiji's Mamanuca Islands, where two of the game's legends set their sights on one another and another player introduces "spy shack" 2.0.
