Alex Beaupain reveals himself for the first time, through the sweet and amused eyes of his cellist. From the backstage of his creations to his most beautiful collaborations (Catherine Deneuve, Fanny Ardant, Françoise Fabian, Clotilde Hesme or Ludivine Sagnier), from the most intimate moments shared with friends (Christophe Honoré, La Grande Sophie, Diastème...) to his most beautiful French and foreign stages, the eye of the camera shows a complex personality, animated by his childish dreams and the sudden death of his first love.

A story not just about a singer, but deeply linked to the post of a disturbed but playful boy who's struggling with letting himself go.
