In 1928, as Paris swings to the Roaring Twenties, the dancer Ida Rubinstein asks Maurice Ravel to compose the music for her next ballet. Petrified and bereft of inspiration, the composer looks back on his life: his early setbacks, the devastation of the First World War, the impossible love he felt for his muse Misia Sert... Ravel delves deep within himself to create his celebrated universal masterpiece, Bolero.
