BMX Legend TJ Lavin welcomes 28 competitors from Survivor, Big Brother, The Amazing Race, and Love Island to The Challenge. With old rivalries, new alliances, messy exes, and fractured friendships under one roof, who will be the first eliminated?

The Challengers are shocked by TJ's latest twist. A Survivor legend looks to cement their dominance in the game, while a crafty Big Brother player might be proving a little too popular with other Challengers.

While some alliances are growing in strength, others are starting to fall apart. A powerful duo starts to raise suspicions in the game, while a pair of newly mismatched Challengers' lack of team chemistry puts their games in serious danger.
