In this eagerly-anticipated makeover episode, the five remaining players head off to a luxury spa to get pampered before shopping for stylish new clothes in Beverly Hills with fashion maven Jeannie Mai. Then in-demand Hollywood hairdresser Ken Paves crafts stylish new looks for the contestants before a limousine whisks them away to see Cirque Du Soleil's "Iris." But before the show begins, each player gets a heartwarming reunion with a loved one flown in to celebrate their big day and see their amazing transformation. Later, back to reality and the ranch, the contestants weigh in and one more is eliminated, leaving the final four players of the season.

The contestants start their week with a holiday food temptation involving Thanksgiving favorites and amazing prizes, including a coveted 3 lb. advantage. Later, trainers Bob Harper, Anna Kournikova and Dolvett Quince prepare a healthy Thanksgiving dinner for the players, and everyone shares what they are most thankful for, with one trainer sharing a surprising revelation. Then it's the toughest challenge of the season so far with an outdoor, one-mile high climb on Jacob's Ladder treadmill climbers. The top finishers win special prizes with a "Pay it forward" twist. Later, one contestant does something considered uncharitable by the others, leading to friction at the elimination table before another player is sent home. Alison Sweeney hosts the series.

The competition shakes up this week when contestants change teams and trainers in a high-stakes, calorie-counting challenge that will determine who each player's trainer will be for the rest of the season. After the teams are re-aligned, dramatic confrontations follow between some players and trainers as they all try to adjust to their new reality. Later, the new teams face their first challenge together -- racing down a water slide on a hill to unscramble block letters that reveal the winning team's prize. Trainers Bob Harper, Anna Kournikova and Dolvett Quince each take their teams off the ranch to spice up their last chance workouts, and later, an especially emotional elimination follows a weigh-in revealing noteworthy results from the trainer/team switch.

This week, only one contestant's weight will count for each team, and trainers Bob Harper, Anna Kournikova and Dolvett Quince get to choose which player will represent their teams. The competition heats up with a cooking challenge in which players and their trainers have to race against the clock to prepare a healthy and delicious low-calorie dish for two special judges -- Season 11 "Biggest Loser" winner Olivia Ward and "Biggest Loser" cookbook author Devin Alexander. Prizes for the winning team include something very special from home. Dr. Huizenga drops by with a special medical guest to visit with the players and give one contestant some very welcome news. And later, the weigh-in reveals whether each trainer chose the right person to represent their team before an elimination leaves one player feeling very betrayed. Alison Sweeney hosts the series.

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. 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!
