The Challenge all-stars meet a new group of professional athletes and entertainers to compete against in the name of charity and to try to become the ultimate Challenge MVP.

One player manages to ruffle feathers with some of the other women, and a flirtatious relationship develops between a Champ and a Star.

Tempers flare on both teams during and after the challenge, and one Star has a total meltdown.

Things get messy when an extreme physical challenge leaves one player injured and another player ready to quit.

With tensions high, the teams play a life-size version of table hockey and vote two unlikely players into elimination.

With an even number of Champs and Stars on the red squad, the Stars orchestrate a plan to take back control of the game.

Alliances are called into question since the Red and Blue teams are now teams of two, and an underwater challenge proves too much for one team.

The players compete in a challenge designed to purge the weakest from the game, and there's an explosive shouting match when one competitor accuses another of cheating.

The four remaining teams battle it out for a spot in the final during a beach challenge that mixes speed, puzzle solving and a bit of pop culture.

The final three teams battle it out in a finale that tests endurance and balance (as well as how strong their stomachs are) in order to take home money for their charities.

The Champs and Stars reunite to find out the audience's favorite moments, answer for some trash talk and settle other unfinished business.
