There are several players in the Naato Part 5 reality show (سریال ایرانی ناتو قسمت پنجم). During the competition, they are asked 10 difficult and sometimes funny questions and the players must find the correct answer together. If the players answer each question correctly, they will receive an amount as a reward, and for each wrong answer, the same amount will be deducted from their reward. Among these players, one person plays the role of NATO . NATO is the one who already knows the answer to all the questions. Apart from the player who plays the role of NATO, no one, even the presenter of the program, knows about the identity of this player.
