18 CBS reality titans are shocked to learn that they will be competing amongst six legendary MTV Challenge veterans. Strategy is turned on its head when TJ introduces a new twist that will put multiple players at risk at the first elimination.

Eight competitors remain to compete in a grueling two-day final challenge where only one man and one woman will split the $500,000 grand prize. While some are fighting for their elusive first championship, others are out for redemption and pride.

After the first contestant is out of the game, a new alliance is formed to target a Challenge veteran, while a power shift in the game has others focused on revenge. After a difficult water challenge, romance blossoms between two teammates.

With the lines drawn, a Challenge vet turns on one of their own in an act of self-preservation. Also, Big Brother alum Paulie opens up about his journey to live in his truth and is presented with the opportunity to reconcile with a former enemy.

When TJ reveals there will be a double elimination, everyone scrambles to ensure their safety. One team hatches a very controversial plan, while two challengers struggle with who to trust in the game, and team Red Flags continues their dysfunction.
