We all know people who feel incomplete, searching for something to make them feel whole. The heartache of separation is difficult on all of us, but it's hard to imagine the struggle for those wondering about family they haven't seen since birth, or who don't know if a loved one is even alive after decades of silence.

The producer of Extreme Makeover: Home Edition created this show with one simple mission-to bring families back together. With the help of a dedicated team of researchers, hosts Tim Green and Lisa Joyner guide people searching for lost loved ones through the emotional journeys that will change their lives forever.

Each episode is full of moving moments and tears of joy, when mothers, fathers, daughters and sons who lost touch for decades are reunited. First we learn the emotional back stories of each family in search of lost relatives. Then with minimal information, the Find My Family team begins the difficult and often frustrating process of sifting through archives and tracking down records until they uncover the missing links. Host Lisa Joyner reaches out to the newly-found family members to let them know that someone from their biological family has been looking for them. Tim Green narrates each story as it unfolds and meets with the people who originated the search. When a family is reunited, they all meet at the Find My Family "Family Tree."
