Set in Las Vegas, this half-hour game show pits clever contestants who think they are aces at history against the boss man himself, Rick Harrison. In each episode, Rick puts his reputation, and his stuff,  on the line. A quick-witted host asks the trivia questions about specific historic items featured in Pawn Stars. In a series of eliminations, the contestants are whittled down from three to one, with the finalist going one-on-one with the star of History's #1 show for a money prize.
