Nancy Nestor (Wendie Malik) sees herself as the perfect wife and mother, and now that her teenage genius son Hal (Justin Long) has been named high school valedictorian, her own moment of public glory is close at hand. Unfortunately, its been over three months since Hal locked himself in an upstairs bathroom to work out the mathematical equations in his head while also watching the cheerleader next door (Danica McKellar) bounce on a trampoline. To Nancys dismay, no amount of threatening or coaxing seems to have any effect on Hal. Noted psychologist Dr. Curly Weeks (Ed Begley Jr.) comes to her aid to develop a program that just might get her obsessive-compulsive son out of the bathroom and onto the graduation podium.
