The Challenge: All Stars

A group of twenty-six competitors are paired up with their enemy from seasons past; as bad blood resurfaces for some, the Rivals quickly learn that to win their share of the $300,000 grand prize, they must be able to work together to survive.

With the four coveted stars claimed, the nine remaining rival pairs without a star are left to figure out how to take possession of one for themselves; at the next challenge, the Rivals are faced with one of their greatest fears: heights.

Tension continues to brew between rivals Kelly Anne and Sylvia; Adam puts himself and his partner Steve's star at risk after coming down with a flu; at the challenge, another Rival pair is divided, leading to big misunderstanding back at the house.

Rivals Aneesa and Ashley attempt to get back in sync after their blow up; Katie tries to school rivals Adam and Steve on playing a more aggressive game; the pressure is on to free up a star, tempting the winning team to make a big move.
