She's very bright but her behavioral problems lead the school to determine she is a danger to the other students. Aggie's problem is that she has telekinetic powers but doesn't know how to control them. Her parents decide to hire a full time caregiver, Karen Ross, who it turns out has powers similar to Aggie's.
