Seoul has been struck by a series of mean-spirited attacks targeting high school heartthrobs, with rocker Ye Sung and basketball player Han Geng among the victims. Word is the next victim will be at Neulparan High School, and the three most likely candidates are steely student body president Si Won, vain dance team leader Hee Chul, and judo team captain Kang In. Studious, bespectacled Ki Bum and breakdancing buddy Dong Hae decide to investigate. Rather than searching for the culprit, however, they're a lot more interested in finding the next target. Meanwhile, the three potential victims are also competing against each other for top pin-up boy status and the fame that comes with it.
