David Gordon (Rob Morrow) is a content professor at NY City College raising his energetic and intelligent 13-year-old daughter Amanda (Kay Panabaker). They have a wonderful relationship filled with mutual admiration and love. Ever since her mother died when she was a little girl, David is the only family Amanda has known, unless you count the "group" of very close friends that forms their extended family. Together these people are a happy and caring bunch of people who would do anything for each other. Life is good. But when dashing entrepreneur John Sullivan (James Denton) arrives in New York and blurts out that he is Amanda's biological father, everything gets turned inside out.

Amanda tries to reconcile the fact that her father hid this fact from her. After all, they shared everything, or so she thought. This is one little tidbit that he never got around to telling her. And the last shoe to drop is the fact that David never got around to legally adopting her. After her mother died he never thought about the fact that he was not her biological father and the subject never entered his mind until John comes back into the picture. John had been married to Amanda's mother then deserted her when he found out she was pregnant. This is all news to Amanda, who is having a difficult time with the sudden information that has been dumped in her lap.

John feels remorse about leaving when he did, the way he did, and now he wants to get to know the daughter he never met. One of the richest men in the country he can afford almost anything and flies Amanda up to Maine on his private jet to spend the weekend at his vacation home, which resembles a resort rather than a private residence. The young girl is impressionable and enjoys all the luxuries John has which include a limousine, a huge indoor pool, and a new fall wardrobe for Amanda. But when John reveals his intention to claim full custody of his daughter, David goes to bat to fight for his daughter. With all the things John can give her, Amanda learns that the most important thing is not material items. It is love, something that David has unconditionally for her, and she for him.

This is a poignant movie that, although the story has been done before, is enjoyable to watch because of the wonderful cast, especially young Kay Panabaker who brings a lot of talent and personality to her character.
