Divorced teacher Marco Sperelli is sent to work in Corzano, a town near Naples. The first day of work he finds in the school only the school-caretaker and few girls and boys in the classroom. He goes out looking for them and discovers that the boys and girls of Corzano live a wretched life in which only power and violence are worth respecting. Sperelli tries to teach something different but he gets their respect only by slapping Raffaele, a budding Camorrist. His presence and work, however, disturb too many persons and he will be transferred.
