The Challenge - Season 28

Meet the veterans and rookies from The Challenge, The Real World, and Are You The One? as they discover that in order to win the $350,000 grand prize, they'll have to work with their worst enemy.

The cast ventures into The Elimination Jungle for the first time, which means alliances are forming, hookups are hot, and friendships are already falling apart.

Replacement rivals enter the house; challengers must work with a rival in an awkward and intimate challenge.

A late-night incident threatens to turn physical; and the contestants are taken aback by the serious implications. In other events, the cast is pulled into a last-minute challenge.

Sleep deprived and mentally broken, the house begins to divide as teams band together to plot against others.

An attempt to hide an alliance threatens friendships, and families within the house.

Two teams are sent home, and the remaining Challengers need to step up in order to keep themselves in the game.

The rivals must work hand-in-hand in their last Mexican challenge to avoid elimination before heading to Mendoza, Argentina.

One final elimination will determine which three pairs will continue on to the final challenge; participants are in for a surprise.

"Rivals III" competitors reflect on their experiences.
