The film recounts the last days of life during the resistance of the anti-fascist Cervi Brothers.

[2] Aldo Cervi, who distanced himself from Catholicism after meeting the Communist Ferrari in the prison of Reggio Emilia, became a promoter, among his six brothers, of resistance to Fascism.

He met the actress of a traveling theater, Lucia Sarzi, who is actually a member of the clandestine anti-fascist movement, Aldo binds himself politically to his ideas.

While his parents host former Allies prisoners in their house, hunted by the nazifascists, Aldo goes to the mountains, with a group of other partisans.

At the end of December 1943, in the Reggio Emilia shooting range, the execution of the seven brothers and Quarto Camurri takes place.
