Survivor - Season 18 (2009)

An all-time Survivor strength record is threatened in a grueling endurance competition.

An overzealous castaway risks it all in the immunity challenge and pays with a tooth, while another castaway finds himself in hot water for not performing during the challenge.

This special edition in a special time period for this week only, provides an intimate look behind-the-scenes at camp life including alliances that have formed, Taj revealing her emotional struggle with being away from her family and Tyson's playful side around the ladies in camp.

Empty stomachs and one castaway's arrogance begin to eat away at the Timbira tribe and a fake immunity idol is introduced into the game.

A power player decides to come into the merge fighting, but his plan may be thwarted before it can be carried out. Meanwhile, an exiled pair makes a shocking discovery.

An unlikely trio find themselves enjoying an epic reward together. Meanwhile, allies are left behind and become concerned that the reward will result in unplanned bonding with a common enemy.

One castaway attempts to pull off a last minute upset with a devious strategic move, while another becomes an outcast and is forced to beg for a second chance.

With her heart on her sleeve, one castaway takes an honest approach to the game but lands herself in hot water with everyone.

A tough decision gives one castaway the chance to sacrifice personal comfort to benefit the rest of the tribe, and a tricky immunity challenge puts brains and brawn to the test as the weary castaways fight for a guaranteed spot in the final five.

In the aftermath of Tribal Council, a shocking betrayal is revealed, leaving one castaway reeling. Meanwhile, another castaway takes a bizarre approach to Exile Island, which has a polarizing effect on the rest of the tribe.

After one shocking vote, a seed of doubt is planted by a carefully constructed lie that, after the second vote, leaves the final two turning on each other at the final Tribal Council.

During a live reunion show the Survivors get together for the first time since being in Brazil to discuss the results of the game.
