In this must-see, exciting live finale, the contestants from this season return for a special reunion and a chance to weigh in one last time - and show America how much weight they've all lost since beginning their weight-loss journeys. Kid participants Biingo, Lindsay and Sunny will also return to show off their inspiring transformations. America's vote will be revealed for who will be the third finalist, eligible for the grand prize, and all the players who have been eliminated will compete for the $100,000 "at home" prize. Then it's the moment viewers have been waiting for, when one of the three finalists will be named this season's "Biggest Loser" and win the coveted grand prize of $250,000!
