Enlightened by her biographer Roxana Robinson and art historian Barbara Buhler Lynes, co-founder of the Georgia O'Keeffe Museum in Santa Fe, this documentary unfolds the fascinating trajectory of the artist who became an icon of American art. Featuring her works, her confidences - between interviews and excerpts of correspondence read by Charlotte Rampling - and her husband's photographs, this film explores the two inseparable passions that marked Georgia O'Keeffe's life and career: Alfred Stieglitz and New Mexico, which she never ceased to travel through, like a pioneer, in order to immerse herself in its Indian culture and its grandiose landscapes.
