"I think I'm nothing." Jane Birkin wrote those words in her secret diary while the world called her an icon. Behind the breathless scandals and effortless style lived a woman haunted by childhood cruelty. Bullied as "half boy, half girl," she hid makeup under her pillow and swallowed sleeping pills for sixty years. She sang the song that shocked the Vatican, created fashion's most coveted bag, and survived cancer twice. Then came December 11, 2013. "Ma fille s'est foutue en l'air" she would later sing. Her daughter Kate's body on the pavement below. How does the girl everyone mocked become everyone's ideal? How does a mother survive the unthinkable? This is Jane Birkin stripped bare. The darkness beneath the light. The whisper that became a roar. Her secrets died with her. Until now. What will you discover about the icon who never believed in herself?
