Journalist Dan Harris hosts a unique game show -- created by Mike Darnell and Mark Burnett -- in which the smartest people from across the country try to answer difficult general knowledge questions without ever getting three wrong in a row. The contestants cannot rely on "saves," anyone's assistance or multiple choice answers: three incorrect answers in a row determine the end of the line. Each competitor must rely on intellect, strategy and stamina to win the game. Executive producers are Mark Burnett and Phil Parsons.
