Stan (Serge Gainsbourg) depressed over his wife's death turns his affection over to his daughter Charlotte (Charlotte Gainsbourg).
In 1984, two years before Charlotte for Ever was released Gainsbourg had written and performed the song Lemon Incest with his daughter, Charlotte Gainsbourg. The song was hugely controversial as it contained references to incest and pedophilia which audiences suspected were partially autobiographical. The movie Charlotte for Ever explored similar themes. Due to Charlotte Gainsbourg's age and the fact that she was playing a character with the same name as her own while her real life father was playing her father in the movie, the movie was reviled and questions about whether Gainsbourg was abusing his daughter were once again raised. As an adult Charlotte Gainsbourg repeatedly defended her relationship with her father, admitting that he had meant to provoke audiences but denying any impropriety or abuse towards herself.
