Born at the dawn of the 20th century in her parents' butcher shop, Jeanne Lavaur dreams of becoming a countess. Refusing to let circumstance define her future, she embarks on an extraordinary journey that carries her through the glamour of Paris during the Roaring Twenties, the devastation of two world wars, and adventures stretching as far as Brazil. Alongside the fearless Céleste and the steadfast Guillaume de Barante, Jeanne navigates love, loss, and history itself, determined to forge her own destiny. Blending archival footage with dramatic storytelling, The Golden Age is an ambitious portrait of one woman's remarkable life across six decades.
