Balanga (1993)

Two students, Strusinski (nicknamed Saint) and Sniper, hate their school and, particularly, one of the teachers with sadistic inclinations and a constant hangover. Not only is he an alcoholic, but also vents his frustrations upon students, nearly grown-ups, tormenting them both physically and mentally. The setting is the unweeded and dirty Warsaw outskirts, among shanties and newly built blocks of flats already falling into pieces, inhabited by all sorts of nobodies, scums and nouveaux riches. In this scenery, the murder of the teacher and police investigation become the central point of the story.
