Sally, Kurt, and Chris are three perfect examples of ""The Boomerang Generation,"" which, as the name implies, refers to kids who grow up, leave home for college, and then come right back to the nest. For their younger sister, 15-year-old Brooke Franklin, the sociological phenomenon is a lifesaver since her parents are always away on vacation. Left to fend for themselves by their globetrotting parents, the four create an unusual surrogate family marked by the usual sibling rivalries and power plays. Somehow they manage to overcome the pettiness, however, in a uniquely genuine attempt to create a nuclear family in the absence of one.
