This is the story of the two babies who were switched at birth. A few years later when one of the girls gets sick and tests revealed that she was not the daughter of the couple who raised her. Eventually she dies. And the couple most especially the mother, search for their real daughter. Eventually they suspect that it's a widower who has their child. Now while they try to find out if she is their daughter, the widower is advised by his attorney not to be so hasty to cooperate, cause if she is their daughter, he might lose her, and she is all he has.

Will, a street-smart teenager, moves from the tough streets of West Philly to posh Bel-Air to live with his Uncle Philip, Aunt Vivian, his cousins — spoiled Hilary, preppy Carlton and young Ashley — and their sophisticated British butler, Geoffrey. Though Will’s antics and upbringing contrast greatly with the upper-class lifestyle of his extended relatives, he soon finds himself right at home as a loved part of the family.
