"La Cage aux oiseaux", "Les Jolies Colonies de vacances", "Lily" or the famous "Zizi": for more than 60 years, Pierre Perret has enchanted people with his popular little fables. At 87 years old, he is the author of nearly 500 songs. How does he view them today? To answer this question, Pierre Perret receives the cameras at his home, in his garden, but also in his attic, where the author keeps his most precious treasures: all his writing books. For the first time, he agrees to open them and to retrace the highlights of his career, and for this he has chosen his own alphabet book. A for Love, C for Censorship, G for Grievances: twenty-six letters, twenty-six words to develop from A to Z the great subjects that are dear to his heart.
