Chris, a high school English teacher, finds himself distracted by a very unruly, know-it-all student who constantly disrupts his class. Somehow he manages to make it through his first year of teaching without killing the mouthy, arrogant student, but is glad to see him finally graduate. Five years later, Chris is shocked to discover that the former student, Riley, has returned. This time he's a teacher and an athletic coach. Unfortunately for Chris, the two have to work together. When Riley shows up in his classroom one evening after school, they both remember that Riley has a detention session he failed to serve prior to graduation.
