The reality series pits the guys against the girls, as the 16 players are divided into single-sex tribes for this sixth edition. The eight men and eight women are stranded in Brazil's Amazon rain forest along the Rio Negro, a piranha-infested river, 35 miles from the port city of Manaus.

The women's tribe elects a reluctant leader, while putting off a candidate who wanted the post. In the reward challenge, the two tribes get a chance to interact and the guys admit to having crushes on some of the ladies. Also: a third player is voted out.
