Superintendent Chessari is sent to run a small police station with a very few staff on the outskirts of Rome- a temporary posting in a difficult area. His deputy, Lorenzo Corsi, a youngster just out of the Academy, clashes with the corrupt reality of the streets. The small police station seems like an outlying frontier post, a sort of backwater where recruits and hot-heads are assigned to rot. Chessari wants a quiet life, with just a few routine operations and plans for career advancement. But his men don't want to stop facing difficult situations also exceeding legality.
