Premise: At times during an illustrious professional wrestling career, Dwayne ``The Rock'' Johnson played the part of the hero. He was physically, mentally and morally tested on many occasions, and it's those experiences that he draws on as host (and executive producer) of this competition series. Johnson's goal is to find a true American hero, and to do so he challenges a group of nine ordinary individuals to face extraordinary situations. Throughout the series, Johnson serves as mentor and motivator, encouraging the contestants to reach far beyond their personal limits. In the end, the player -- as determined by viewer votes -- who overcomes obstacles he or she never thought possible walks away with up to a million dollars.
