ALTERNATE SYNOPSIS:
Kyo Doo-Sik (Jeong Jun-Ho) is a gang vice-leader after dropping out of high school. But Doo-Sik's stunted education makes him the laughing stock of the gang, and he's commanded to return to his studies by his boss. Disguised as a 19-year-old, Doo-Sik has a hard time at school: he's whipped, blackmailed, and bullied by both teachers and students ten years his junior. But before long, Doo-Sik begins to notice violent corruption in the school. The school foundation director is funded by a gang organization, and demands that teachers give rich students good marks so that they can get into top colleges. The loathsome director sexually harasses female teachers and defends a student's mother who beat a teacher. When a student Doo-Sik knows is beaten to a pulp then expelled, Doo-Sik rallies his henchmen and fellow students and sets out for revenge. |
