Christian "Mac" Barrett is a fifth grade "Godfather" who runs a business operation out of the fourth stall of the boy's bathroom and has the answer to everyone's problems - be it help with a bully, test answers, candy, or even dates with girls. But his business is threatened when Staples, a bookie and high school dropout, sets up shop in Mac's school. Now Mac has to deal not only with the day-to-day problems of running his business, but also a legendary villain and his group of high school lackeys who seem intent on taking down his operation for good.
