Towards the end of the day, fatigue starts taking its toll and disaster strikes when the hand of a drowsy worker is mangled by a machine. Workers Pautasso (Folco Lulli), Martinetti (Bernard Blier), and Cesarina (Elvira Tonelli) decide to form an "ad hoc" committee and speak to management and state their case that the 14-hour work day needs to be shortened by one hour to avoid accidents arising from exhaustion. Their request is ignored and they only receive admonishments to be more careful. Moreover, a subsequent attempt by the workers to emphasize their grievances by staging a walkout an hour early on the next evening results in a humiliating defeat when they lose their nerve and stay until the usual time.
