In a brand new limited series, twenty-two of the most iconic, boldest, and fiercest Challenge All Stars from the original The Real World and Road Rules return for a second chance at the ultimate competition as they vie for their shot at the $500,000 grand prize. Hosted by TJ Lavin, the nine-episode season will follow competitors as they face unprecedented, over-the-top challenges set in the Andes Mountains of Argentina. The Paramount+ original series welcomes back many of the greatest reality titans the franchise has ever seen, including some who haven’t competed in more than two decades.

Each year, seven strangers in their twenties, from different backgrounds and countries, are chosen to come live together in a major city.
