The contestants are off on the adventure of a lifetime, headed to Utah Olympic Park in Park City, Utah, where they'll train like champions and get to meet some incredible Olympic athletes. Dolvett introduces the players to Olympic gold medalist Apolo Ohno, who talks about his own "Second Chance" - this season's theme - and works out with the contestants inside the spectacular Olympic Oval arena. Then the contestants get to compete in the sport of curling, after an introduction to USA Curling team members Jessica Schultz, Debbie McCormick and Anne Swisshelm. The fun continues at the base of the bobsled track, where words of motivation from USA Bobsled Team members Lolo Jones and Jazmine Fenlator get the remaining seven players fired up about the fast-paced sport. But for this week's challenge, they won't be racing down the track. Instead, they will be running more than a mile up the bobsled track, a challenge made far more difficult by the elevation of over 7,000 feet. Also this week, Bob designs an Olympic-inspired workout that puts all the players to the test, and Jillian tries to help a contestant still struggling to embrace her self-worth. Travelling and being away from the ranch environment leaves many contestants worried about their weight loss this week. Those fears intensify at the weigh-in, where surprising results push two players below the yellow line and the other contestants must decide which player is going home.

"The Biggest Loser" returns with 15 inspiring contestants - including the show's first celebrity player, Ruben Studdard, an uplifting "Second Chances" theme and powerful new roles for trainers Bob Harper, Jillian Michaels and Dolvett Quince. For the first time ever in the show's history, trainers sat in on casting sessions and helped select the new contestants, and also received a "trainer save," allowing each one to save one eliminated contestant from going home. Contestants eager for a second chance to reclaim their health and re-write their futures include "American Idol" winner Ruben Studdard, this season's heaviest contestant at 462 pounds, David Brown, who lost his first wife to an almost decade-long battle with cancer and is now fighting for his life so he can be there for his daughters, and Tanya Winfield, a single mom addicted to food who grew up with a teenage mom addicted to drugs, who is eager to break the cycle of addiction in her family. Also competing this season will be Olympic weight lifter Holley Mangold, hoping to get in the best shape possible for a second chance at gold in the 2016 Olympics, and Matt Hooper, who postponed his wedding to be on the show so he could give his fiancé the best physical version of himself.

This week kicks off with all of the eliminated contestants returning to weigh-in, and one lucky player getting the chance to return to the competition. Then it's off to a grueling kettle bell beach challenge that promises the winning player a hefty prize. Fan favorite and former "Biggest Loser" contestant Abby Rike pays a visit to the ranch and inspires the players with her own "Second Chance" story. Later, the contestants head to the race track for words of encouragement and a fun workout with popular NASCAR driver Carl Edwards. Then one player reaches "One-derland" at the weigh-in and another is sent home before host Alison Sweeney gives the remaining contestants some very exciting news.

It's one of the most eagerly-anticipated episodes of "The Biggest Loser" season - the makeover episode! The fun begins with fashion expert Tim Gunn, who works his magic helping the contestants select stylish new outfits to flatter their new slimmer selves. Then celebrity hairstylist Ken Paves, whose clients have included Jennifer Lopez, Victoria Beckham, Lady Ga Ga and Eva Longoria, crafts incredible new looks for each of the remaining seven contestants, leading to amazing and dramatic transformations. Then they are whisked away to enjoy a special night out and heartwarming, emotional reunions with loved ones flown in to celebrate their big day. Later, it's back to reality and the ranch, where two players fall under the red line at the weigh-in and are eliminated, revealing the final five contestants of the season.

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.
