It has been four years since the events of the first movie. Seventeen-year-old Sean Anderson (Josh Hutcherson) is caught by the police after a brief chase on his dirtbike which ended with him driving into a swimming pool while trying to evade them. Minutes later, his stepfather Hank (Dwayne Johnson) arrives where a police officer (Stephen Caudill) who is friends with Hank tells him that Sean had broken into a remote satellite research center. The police officer also tells Hank that he has talked Mr. and Mrs. McGillicutty (the owners of the swimming pool) out of pressing charges. Hank takes Sean home where his mother Elizabeth (Kristin Davis) is not pleased with his actions or the fact that he and Hank don't get along well.
