Everyday people battle a variety of trivia questions and a 40-foot wall for a chance to win millions of dollars. Each pair of deserving contestants, from siblings to spouses to best friends, has a plan to use the life-changing winnings for good things. But defeating the wall is no easy feat. Executive producer LeBron James' 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.

Nearly 50 years apart, grandmother and granddaughter duo Nellie and Taylor from Quarryville, Pa., take on the wall.

Deidra, a midwife and health care specialist, and her husband Damon, a high school principal, devote their lives to helping others; the new Superdrop brings big surprises for the Detroit duo.

Michael, a firefighter and carpenter, and Holly, a kindergarten teacher, from Knoxville, Tenn., look to take aim at the wall.

Mother-daughter duo Alex and Jodie, both nurses from Oklahoma City, Okla., share a passion for rescuing animals and together have fostered more than 150; the two hope to hit the $1 million mark on the wall.
