The castaways turn the huts into rafts and are finally rescued, to great fanfare. On the 1-year anniversary of their rescue they all meet in Hawaii for a reunion, and decide to take a short cruise. The weather starts to get rough, and they get stranded on the same island again.
Notable for the absence of Tina Louise, who refused to join any reunion. She was replaced by Judith Baldwin. (Aired in two parts on October 14 & 21, 1978)
