Genre: Reality, Adventure
Premise: The most recent incarnations of ``The Challenge'' paired enemies in ``Rivals'' and old flames in ``Battle of the Exes.'' The 23rd season incorporates both rivals and old flames in a fight for ``Real World'' supremacy. The 28 contestants -- all former ``Real World'' cast members -- are grouped on seven teams representing the Austin, Brooklyn, Las Vegas (both seasons), Cancun, New Orleans, San Diego and St. Thomas ``Real World'' seasons. Competing in the usual challenges that put a high priority on strength and stamina, each set of teammates must form a working partnership without the emotions of painful grudges and broken hearts leading to elimination. The ultimate winners divvy up $350,000 in prizes.
