Episode 1: Every Second Counts

Meet the celebrity judges who know what it means to give big: Jamie Oliver, the world-famous chef who is passionate about improving the lives of England's youth; Malaak Compton-Rock, mother of two and the wife of comedian Chris Rock, who has dedicated her career to making a difference; and Tony Gonzalez, the NFL star who's felt the rush of giving back.

After each challenge, the judges will decide who to eliminate based on four criteria: creativity, leadership, presentation and accomplishment.
