Ovidio, Peppe and Giacomo are three employees who work with electronic calculators in a large company. The stress due to the monotony and alienation of work pushes them to perpetrate acts of vandalism and violence, which results in a series of crimes committed with cruelty and sadism. A retired senior police commissioner begins the investigation, managing to identify two of the three culprits. The first to be arrested is Peppe, who hangs himself the first night he spent in prison. Ovidio dies in a firefight with the commissioner. Giacomo, instead of worrying about the situation, meets two other fellows in order to plan the next misdeeds.
