Un groupe de Bretons réfractaires et pacifistes est envoyé en Algérie. Ces êtres confrontés aux horreurs de la guerre deviennent peu à peu des machines à tuer. L’un d’entre eux ne l’acceptera pas et désertera en emmenant avec lui un prisonnier du FLN qui devait être exécuté le lendemain.

Two friends, Jeanne and Johanna, are members of a rinky-dink orchestra, ”Les Sirènes”, playing the Decazeville region in everything from ballrooms to beauty pageants. While Jeanne is introverted and romantic, Johanna is outgoing and sensual. A talent competition in Toulouse catapults them to success thanks to a sound engineer’s ruse: Johanna mimes on stage to a play-back of Jeanne’s voice. The crowd goes wild, a star is born. Johanna has it all: great presence, great voice. Gigs follow, and their ill-shared success proves devastating for our two heroines, who learn that in a society where appearances are all, there is one thing that cannot be bought: their friendship.

The extremely sharp-witted and articulate young officer Cyrano de Bergerac is hopelessly in love with his cousin Roxane. Yet his love remains undeclared, for he is convinced that she will reject him because of his unusually prominent nose. Instead, Cyrano expresses his love for Roxane anonymously by crafting beautiful love poems on behalf of his shy but handsome friend Christian, who also happens to be in love with her. Roxane becomes smitten with the author of the poems, whom she believes is Christian, though she has unwittingly fallen in love with Cyrano himself.
