Behind the Screen: The Challenge: Spies, Lies and Allies - Trailer

For over two decades, MTV's The Challenge has been the proving ground where reality TV's fiercest competitors come to cement their legacies. What started as a Real World/Road Rules spinoff has evolved into one of the most physically and mentally demanding competition series on television.

The franchise's expansion — with spinoffs in the USA, UK, Argentina, and Australia — speaks to a global appetite for the brand of cutthroat competition and alliance-driven gameplay that Vevmo's community has been tracking since 2007.
