12-year-old Preston Waters is tired of his pain-in-the-butt brothers and stingy parents. One day, rich, convicted money-launderer Carl Quigley nearly kills him in a parking lot and gives him a blank check by mistake. So he boots up his computer, makes out the check for $1 million, adopts the pseudonym "Mr. Macintosh", and gets spending. But Quigley wants his money back--it was supposed to be cashed by another man with a blank check and handed back to him. Can Preston keep up the facade? Will Quigley and his goons get their money back? And will Preston learn how valuable money really is?—Newton Haights
