The Countdown has begun! Before Tori and Bobby say, "I Do," there's a million things left to do! Tori has her final wedding dress fitting and she sits down with Carlin to come up with a hairstyle for her special day! Meanwhile, Gil, Nathan, and the middle boys get to work on cutting and trimming trees for Tori and Bobby's "winter wonderland" wedding decor. Will the boys' lack of progress put Kelly Jo in a panic? Meanwhile, with Baby #3 on the way, the Paines take a family trip to the Doctor for Erin's ultrasound. Last, in honor of their 30th anniversary, Gil and Kelly Jo have a memorable date night and attend Lawson's Charity Christmas concert. But when Nathan jumps up on stage unannounced, the family's in for an unexpected surprise!

In this new special, hear from the Bates family as they speak for the first time about their experience shooting the show. They'll look back and reflect on seven seasons, share funny stories from "Behind the Scenes" and discuss how being on TV has impacted their lives and those of others.
