The two new tribes are dropped off of a truck and into the highlands of Brazil. Jeff announces both tribes will then vote for one person based on first impressions. The red tribe, Jalapao, vote Sandy. The black tribe, Timbira, vote Sierra. Both tribe mates are upset that they were the first to be singled out, but are able to skip the trek to camp and fly by helicopter. Meanwhile, all the other tribe mates have to walk in the heat to their campsite, carrying all their supplies. While they are alone at their respective campsites, both Sandy and Sierra read a letter with a clue to a hidden immunity idol. Sandy attempts to find the idol, while Sierra decides to make a shelter instead. The next morning, both tribes meet for their first Immunity Challenge which is won by Timbira. The Jalapao tribe returns to camp and many tribe mates agree that Sandy worked hard during the challenge, and that Carolina is bossy. But Sandy is not convinced that she is safe and continues looking for the immunity idol.
