There is nothing strange about the murder. It is committed in broad daylight, the murderer walks out on it with blood on his hands and bloody footprints, and he is taken care of immediately. The strange thing is he doesn't care. For him the case is clear and finished, and he has nothing more to live for, so throughout the trial, as long as possible, he just stubbornly keeps his silence, leaving the world in a mystery.
Thanks to an arduous lawyer, that mystery is gradually revealed. He is reluctant to take the case, since the victim of the murder was like a father to him, and when he wants to back out, it is too late. He has to go to the bottom of it, which certainly isn't easy, because of his imposed client's persistent silence.
Franco Nero makes an unforgettable impression and impact as the quiet murderer, who refuses any communication, until he is faced with a childhood friend of the days of the war 1944 in Monte Catini, whose father was executed after the war as a collaborator with the Germans, although he was no more than an interpreter, forced into their service. A grim drama is revealed in flashbacks memory by memory, which can leave no one untroubled. It's just a novel, but it is too realistic and convincing not to be founded on truth. In fact, there were innumerable cases like this, and the Germans actually executed hundreds of thousands of innocent civilians just for reprisals for nothing.
