It's all about families in the new edition of The Biggest Loser, which features four husband-and-wife teams and four parent-adult child teams trying to lose weight through diet and exercise as they compete for a grand prize of $250,000. Trainers Bob Harper and Jillian Michaels fly around the country, surprising their teams with the news they've been chosen for the show. Then it's off to The Biggest Loser ranch in California, where the contestants get a wake-up call from the show's doctor about what ages their bodies really are vs. their chronological ages because of obesity. Then the eight teams compete in their first challenge -- and the lucky winner gets immunity from this week's elimination. Alison Sweeney hosts the hit weight loss series.

It's the last episode before the season finale, and time for the final four contestants to reflect on their weight loss journeys and the amazing progress they've made. They'll try on their former "big" clothes and watch highlight videos with their trainers showing just how far they've come. Then, in their final challenge of the season, the contestants will have to carry all the weight they have lost as they race around a track, shedding one week's weight loss at each pit stop until they cross the finish line. Later, at the final weigh-in, two players fall below the yellow line, and then make their heartfelt pleas to viewers as America will once again decide which of the two will become the third finalist at the season finale.

This season, the remaining five contestants are whisked away to New York City for amazing makeovers that will show how far they've really come in their weight-loss journeys. After getting new hairstyles at a top salon, the contestants are off to Macy's, where "Project Runway" winner Christian Siriano helps them pick out new outfits to show off their skinnier new figures. Later, after their transformations are complete, the made-over contestants are revealed on the "Tyra Banks Show," unaware that their loved ones are waiting to surprise them! After enjoying a day in New York with their family members, they head back to the "Biggest Loser" ranch. There, the contestants are tested with a wild challenge that becomes a huge victory for one player struggling to overcome her fears. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.

It's Thanksgiving week at the "Biggest Loser" ranch, and contestants will be celebrating with turkey, football and very special guests! First, NFL Super Bowl MVPs Jerry Rice and Steve Young stop by to put the contestants through NFL-style drills. Then celebrity chef Rocco DiSpirito helps the contestants make a healthy version of a traditional Thanksgiving dinner. Later, the contestants are really thankful when they receive special videos from home. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.

America's vote is revealed and the third finalist is announced; one of the finalists is named this season's "Biggest Loser"; a sneak preview of season seven.
