In 1944, newly married Copper Reilly arrives in Paris soon after the liberation. While the city celebrates its freedom, she's stuck in the prison of an unhappy marriage. When her husband commits one betrayal too many, Copper demands a separation. Alone in Paris, she finds an unlikely new friend: an obscure, middle-aged designer from the back rooms of a decaying fashion house whose timid nature and reluctance for fame clash with the bold brilliance of his designs. His name is Christian Dior.
