Reality titans from the CBS universe compete in the most unpredictable and demanding game of their lives. With an ever-changing game, players are in a constant state of paranoia, unable to trust anyone but themselves. The CBS all-stars compete for a chance to join the upcoming global “War of the Worlds” championship.

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.
