Teams of two everyday people battle trivia questions and a 40-foot wall to win up to $13.6 million. Each pair of deserving contestants, from siblings to spouses to best friends, has a plan to use the life-changing winnings for good. But defeating the Wall is no easy feat. Part smarts, part luck and part guts, this game is a true test of both knowledge and poise. With momentary changes between fortune and failure, the outcome is as unpredictable as the bounce of the ball.
