Rival high schools battle for superiority in this Japanese teen action sequel directed by Takashi Miike. Having become the dominant force at his own school, Genji (Shun Oguri) and his 'G.P.S. Alliance' now face a direct challenge to their position from 'The Army of Killers', a rival faction at nearby Hosen Academy. Choosing to ignore the bloody history between the two camps, Genji soon breaks the fragile truce that has until now kept the two sides apart, thereby setting the match to a long-dormant gang war.
