Summary: Lucien Ginsburg, a rebellious French Jewish boy with a grotesque imagination, hates playing the piano like his father, a bar professional, and manages to be admitted to Montmartre Academy as a painter, where he befriends an SS officer who helps him survive the occupation. After the war, he chooses to become a performing artist and adopts the stage name Serge Gainsbourg. His unorthodox songs bring him success, even his parents's approval, and lots of lovers, yet his marriages are all utter failures.
