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.

In this social experiment, smoking-hot celebrity singles think they're running away to paradise for a once-in-a-lifetime romantic vacation full of fun and sun. But just as the party is getting started, unwanted guests arrive to break up their good time.

Memorable competitors from MTV's The Challenge invite viewers to their hometowns for in-depth interviews that shed new light on their personal lives, interests and more.
