Naked Violence

In the evening school of Andrea and Maria, in Milan, a group of eleven boys, mostly bad boys and small street criminals between thirteen and twenty, brutally murders the teacher Matilde Crescenzaghi with no apparent reason. The police begins to investigate the murder, but finds no clear evidence or sufficient information to shed light on the mysterious affair. Pressed by the investigating judge who wants to close the case, but also seized by remorse and by their own conscience as a policeman, the police-chief Luigi Càrrua entrusts the case to the Commissioner Lamberti, his friend and collaborator.
