Episode four of Survivor: The Amazon details further erosion amongst the all-male Jaburu tribe as Matthew Von Ertfelda is left behind as the other men forage for food. Meanwhile, the all-female Tambaqui tribe decides it is high time to choose a leader. Elsewhere, the Reward Challenge involves fire, rope, and flags, while the Immunity Challenge tests the players' fishing prowess. Meanwhile, Christy Smith, the only deaf contestant, grows more self-confident with each passing day. The same, however, can not be said for another female player, who at the end of the episode is voted off.
