Plot synopsis: The time is the late 1920s, and Angelo and Tonino are two brothers traveling around the country in a rattle-trap truck, showing moving pictures to any group of people willing to pay. When they arrive in the region of Emilia-Romagna, Angelo strikes up a relationship with a wealthy marchesa connected to the fascist movement. Tonino, on the other hand, starts to follow the rebellious Giovanni, locked up for his anti-fascist stance, and the farmers who have joined in the anti-fascist forces. As the rebels are either murdered or put in prison, Tonino becomes more and more commited to their cause - especially after Giovanni is killed. When a silent movie on the condemned and dying Christ is shown on the brothers' screen, Tonino stops the action to project some slides he has taken that show who murdered Giovanni - in an action that calls for his brother and the rest of the bystanders to finally make a decision on where to place their loyalties.
