With their sights set on "The Volunteer State," the Extreme Team returned to Nashville, Tennessee, inspired by the state that lives by the standard of neighbor helping neighbor. Devastated by the 500-year flood on May 1st of this year, one image continues to endure: News stations across the country featured footage of a school building floating down the interstate. What people didn't know was that the Sweatt family had been running the school since 2003. Despite the extensive damage to their own facility, Brian and his wife, Barbara, spearheaded recovery efforts and have helped over 200 families to date. On September 10th, the "Extreme Makeover: Home Edition" designers teamed up with some of country music's brightest stars to take the bull by the horns and deliver a new school to some deserving students.

Andre and Jasmine Anderson have never allowed their visual impairment to slow them down, but rather have faced it head on, and established the Disability Awareness Center in Maple Heights, Ohio, to help others who are struggling with sight loss. The couple and their sons learned they would be recipients of a home makeover while aboard the public bus that they ride every day. The "EM: HE" team surprised them on the bus and revealed plans to give them a new "smart" home, equipped with technologies that support people with disabilities.

The holidays get into full swing when international superstar Mariah Carey helps the "EM: HE" team create a Winter Wonderland in Pensacola, Florida for Finis Gaston and his niece and two nephews. The spirit of giving is all around, from the moment Mariah Carey steps off the "EM: HE" bus to give this deserving family the surprise of a lifetime to the snowy reveal as Christmas parade revelers dance to her new holiday hit, "Oh Santa!," and volunteers and the community welcome the family to their festively-decorated new home.
