Survivor: Season 4, Episode 5

4 - 5: The End of Innocence

One tribe wins the right to take the opposing camp's food and supplies after completing a reward challenge that requires the teams to collect segments of four deconstructed tikis and put them together. For immunity, the tribes must create a distress signal that can be easily seen from a rescue boat. The best signal wins. The losing team goes to tribal council and votes out the fifth person from the game.
