An honorable man is murdered because he knew too much about the dreadful deeds of the ruling class who puts gain before any human consideration. A happy family is destroyed by this murder. The son plunges into the heart of the tragedy and finds himself facing a double mission: he must honor his dead father by making his killers pay with their own blood and re-establish family harmony.
