2030. In a university lecture hall, Antoine, a young professor, gives a lecture on the unconscious transmission of family secrets. To explain how behaviors are repeated from generation to generation, he tells his students the story of Maurice, Guy and François… Three generations of men who did not know their father and abandoned their family to live their absolute passion for the musical.
All of them unknowingly reproduce the same story, until the day François decides to break the law of silence and stop the infernal cycle.
