Niko Kaylor, the terror of his middle school, doles out wedgies and collects money he doesn't need. When he is forced to begin keeping a journal of his activities to curb his bullying ways, he secretly turns his diary into a how-to guide for bullies. Now, against the wishes of his peers, Niko plans to conquer his middle school and teach everyone a lesson in bullying, including his teachers.
