(from FOX's web site, September 2008) THE MOMENT OF TRUTH will put participants to the test -- the lie detector test -- to reveal whether or not they are telling the truth for a chance to win half a million dollars. On THE MOMENT OF TRUTH, the challenge is simple -- answer 21 increasingly personal questions honestly, as determined by a polygraph, and win up to $500,000. This is the only game show where participants know both the questions and the answers before they begin to play. Prior to playing, participants are strapped to a lie detector and asked a series of questions by a polygraph expert, who records their answers. At any time, between the polygraph and the televised game, participants can change their answers or walk away from the competition. To win $500,000 participants have to tell the truth. Of course, the questions are easier when the stakes are low â€“ but as the prize amount increases, they will be challenged to fess up to matters they might normally lie about. The touchier questions could be especially revealing because participants reveal their answers in front of spouses, relatives and friends, hanging on every word. What deep dark secret will someone divulge for hundreds of thousands of dollars? THE MOMENT OF TRUTH is being produced in 23 other countries, including Spain, Brazil, Germany, France, Italy and the United Kingdom.
