The Challenge: Vendettas

Twenty-eight competitors arrive in Thailand ready to take home big money. But no one is ready for the hell that's about to break loose when old rivalries and broken romances come to the surface.

The war between Wes and his team intensifies. And the Champions reach a new low when they intentionally pit best friends against each other in The Ruins.

Evan finds romance. But is it love or strategy? The rest of the Champions continues to battle over Wes's real intentions in the game.

Champions struggle with team camaraderie: Katie and Tonya continue to have their buttons pushed and a past grudge is revealed leading to a shocking departure from Thailand.

Wes, Johanna, KellyAnne and Cohutta's "love web" gets pushed to its limit making it time for one to go home, while having an alliance proves to not always be a benefit during deliberation.

The Evan, Kenny, Susie, Johanna alliance continues to reign supreme, and Johnny becomes increasingly insecure about his place in the group.

Winding down to the final challenges, the two teams are tied, but the strength clearly lies with the Champions. And the Challengers desperately need a win in order to get rid of their weakest link.

Anger and frustration take hold of the Challengers as KellyAnne and Dunbar wage war over unresolved sexual issues, and Brad makes a decision that could change the course of the competition.

In The Ruins, Dunbar and Kimberly fight to keep the Challengers' dream alive. And, in a strategic move, the Champions consider throwing the next challenge to give them a stronger position in the final. But not everyone agrees.

The Champions become paranoid that they could lose in the end if one worrisome team member fails to pull their weight. The Champions and the Challengers take part in a nail-biting finale - a grueling race for the $300,000 prize!
