The Class (2007)

An average guy of an Estonian high-school decides to defend his bullied classmate. This starts war between him and the informal leader of the class. As teenagers' honour is a touchy thing, everything ends in bloodshed.

One of several global dramas that reportedly culled direct inspiration from the infamous Columbine High School Massacre (and evidence, given its geographic origins, of that tragedy's global impact), Ilmar Raag's harrowing Estonian drama The Class (AKA Klass, 2007) unfolds in an Eastern European high school overrun by psychotic bullies. Amid this morass, 16-year-old Joosep (Part Usuberg) suffers from constant, sadistic belittlement and humiliation. One of his torturers, newcomer Kaspar (Vallo Kirs), soon changes sides and offers to protect the victim, as a kind of bodyguard, but in time, per human nature, the bullies also turn him into a pariah. One act of systematic humiliation too many soon pushes the two boys over the edge and sets the stage for an unremitting bloodbath of vengeance. Raag also authored the original script.
