Conceived as a journey through time and films, Salut & Fraternité retraces the career of filmmaker René Vautier, comparing his testimony with those of other filmmakers (Jean-Luc Godard, Yann Le Masson, Bruno Muel...). Questions are raised about commitment, the role of the filmmaker and his films in society, the need for a cinema of social intervention and counter-power... with censorship constantly in the air.
