By meeting his former comrades in combat, the film follows the journey of Yves Mathieu, anti-colonialist in Black Africa then lawyer for the FLN. When Algeria became independent, he drafted the Decrees of March on vacant property and self-management, promulgated in 1963 by Ahmed Ben Bella. Yves Mathieu's life is punctuated by his commitments in an Algeria that was then called "The Lighthouse of the Third World". The director, who is his daughter, returns to the conditions of his death in 1966.
