Host TJ Lavin brings together the decorated Challenge Legends and the Global MVPs from Argentina, Australia, the UK, and the U.S.A. for a groundbreaking and grueling new competition.

Twenty-two Challenge All Stars return for a second chance at the ultimate competition and a $500,000 grand prize.

An infamous ice-cold throwback challenge leaves some players in a compromising position; years-old tensions arise between two all-star competitors.

Reunited in the house, two best friends clash, reopening decades-old wounds that threaten their relationship.

Relationships are questioned as the competitors jockey to avoid being sent into elimination; some Global MVPs begin to distrust the Legend players' gameplay, and a scheming Challenger's double-dealing leads to an explosive confrontation.

The fight for $500,000 and the title of Challenge World Champion is on as teams push themselves to their limits across the South African countryside in their most brutal test yet.
