Legends will fall. A new champion will rise.
Each Challenge pits numerous cast members from past seasons of reality shows against each other, dividing them into two separate teams according to different criteria, such as gender, which show they first appeared on, whether or not they're veterans or rookies on the show, etc. The two teams compete in numerous missions in order to win prizes and advance in the overall game.

With the Finals approaching, players scramble to stay out of elimination. No one can predict who the Compromised Agent will choose to battle in The Lair. Just when the players think they are in the clear, TJ drops a bomb that puts everyone in danger.
