Synopsis by Hal Erickson
Days 19, 20, and 21 pass by quickly for the ten remaining castaways on the tiny South Pacific island of Nuku Hiva -- but not quickly enough to suit some of the players. The time has come for the two separate tribes, the Rotu and the Maramuu, to merge into a new tribe called the Soliantu. With the merger comes a brand-new rule, one involving the persons granted immunity on this and future episodes. And as the sun sets on day 21, the ten survivors are reduced to nine.
