The poet Jean Sénac, also a radio host, chose to stay in Algeria after his country's independence in 1962. Ten years later, a protester and libertarian, he was monitored by the regime's police. His poems attract a popular audience and his show is a real success with young people. Also, when Hamid and Belkacem, two students, learn that the play they wrote and presented at the first national Algerian theater festival is downgraded under the pretext that they performed it in French, their pain will be alleviated by the presence behind the scenes by Jean Sénac who congratulates them. The latter will become close friends of the poet and witness his fight for the freedom and culture of Algerian youth. A fight which would lead Sénac to martyrdom: one night in August 1973, he was assassinated in the cellar which served as his apartment. Hamid is accused of the murder.

By ending the life of Jean Senac on August 30, 1973 in Algiers, his assassins believed they would silence him forever. They were wrong since his voice is a little louder every day. Witnesses to these craze: the publication of the complete works of this great poet, the countless conferences and radio broadcasts devoted to him and finally the production of films such as "Jean Sénac, the blacksmith of the sun". The moving and overwhelming testimonies of those who knew him, the unpublished film archives, the generous voice of the poet on the radio, the discovery of his travels in the territories of poetry and politics make this film a precious document on the life of Jean Senac.

In 1967, Visconti came to Algiers for the filming of The Stranger with Mastroianni and Anna Karina. Camus, during his lifetime, had always refused to allow one of his novels to be brought to the screen. His family made another decision. The filming of the film was experienced in Algiers, like a posthumous return of the writer to Algiers. During filming, a young filmmaker specializing in documentaries Gérard Patris attempts a report on the impact of the filming of The Stranger on the Algerians. Interspersed with sequences from the shooting of Visconti's film, he films Poncet, Maisonseul, Bénisti and Sénac, friends of Camus, in full discussions to situate Camus and his work in a sociological and historical context. “The idea is for us to show people, others, ourselves as if they could all be Meursault, or at least the witnesses concerned to his drama.”

Jean Sénac, born in Béni Saf in Algeria in 1926 and died in Algiers in 1973, is today considered one of the great French writers and poets and the only one of his reputation to have accompanied the Algerian revolution before November 1954. part of all the debates and got involved, very early and with immense enthusiasm, in a work of commitment which ended badly. His poetry, his sexual preferences and his political lyricism work against him: rejected as much by the Pieds Noirs as by the FLN activists then by the power in place in Algiers, Jean Sénac was assassinated in 1973 at his home in Algiers, in circumstances never clarified.
