This choral documentary takes as its starting point the legendary show L'Osstidcho (1968), and tells the story of four young artists in tune with their times, who both shook the pillars of the temple and paved the way for generations to come. The voices of Robert Charlebois, Mouffe, Louise Forestier and Yvon Deschamps are echoed in the words of artists, historians and sociologists of every generation. We retrace the genesis of L'Osstidcho and discover how this flagship of the Quiet Revolution continues, consciously or unconsciously, to influence us socially and culturally.
