In this must-see, exciting live finale, the 15 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. Those 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.

The contestants celebrate Thanksgiving week with a special challenge - racing to load boxes of Thanksgiving food into trucks headed to help tornado victims in Moore, Oklahoma, where one player has a special connection. Members of the winning team are very thankful for their prize - a holiday dinner shared at the ranch with loved ones flown in for the celebration. Emotional reunions follow, as the winning team, their trainer and their family members gather for a Thanksgiving feast and share what they are most grateful for. Also, one player gets encouragement from his trainer to talk to his family about a long-kept secret, and the show catches up with one of season 14's child ambassadors, Sunny, to see how she is doing today. Then it's time for weigh-in and another elimination, which leaves one trainer giving a very tearful and emotional farewell to one of their players.

The dreaded "week 2 curse" is on all the players' minds, especially when they learn that only one person's weight on each of the three teams will count at this week's weigh-in. And they won’t know who it is beforehand, only when a roll of the die at the scale determines who will represent the red, white and blue teams. One lucky group will get a weigh-in advantage if they win the first challenge of the season; a water-bucket race that ties each team’s fate together in more ways than one. Also this week, one player gets sobering health news from Dr. H, another contestant connects with a very special family member and the show catches up with one of last season's popular child ambassadors to see how they are doing now.

Host Alison Sweeney kicks off this week's episode with a shocker – one of the contestants is going home and taking their trainer with them, and their weight will be the only weight that counts for their team when they return in time for the weigh-in. A simple spin of the wheel determine who will be chosen among the players, who would love to reunite with loved ones but are understandably anxious about the intense pressure they’ll face trying to lose enough weight to keep their whole team safe another week. Meanwhile, one trainer brings their contestant back to a sport they once loved, and two players celebrate milestones at the weigh-in before another contestant is sent home.

This week, the contestants are surprised to find that the gym is empty - and the only equipment they’ll be able to use is equipment they've successfully bid on with "Biggest Loser" bucks in the show’s first ever auction, run by host Alison Sweeney. Trainers Bob, Jillian and Dolvett and the players have to get creative to make the most of their limited equipment. Later, one player opens up to her trainer about her difficult childhood, and all of the contestants re-charge their spirits with a very special treat - getting to skype with their loved ones back home in emotional, heartwarming family visits. Then it's time to head to the gym for a very emotional weigh-in. Also this week, the show catches up with season 12 fan favorite Vinny Hickerson.
