The Human Factor (2013)

Milan. Behind the windows of the city’s buildings are private rooms and private lives. And a man, Inspector Monaco, weary of his job since his wife died three years ago. According to the rules for survival that he has set himself, he wants no further contact with other people or with the stench of violence; he just wants to do paperwork. This night, however, sees the arrival at police headquarters not just of the Ullrich murder case, but also of Monaco’s daughter Linda, arrested for possession of a firearm. Dawn casts light on a new and grim reality, and the Inspector must decide how to face it: as policeman or father. Searching for himself, he will find Linda again, as well as a truth which is not what it seemed.
