Prior to the show, a contestant is hooked up to a polygraph and asked between 50 and 70 questions. Without knowing the results of their polygraph, they are asked 21 of those same questions again on the program, each becoming more personal in nature. If the contestant answers honestly as confirmed by the polygraph, he or she moves on to the next question. A person may stop at any time and collect the money they have won. Answering all 21 questions honestly wins $500,000. One lie and the participant loses everything and their game is over.
