In the summer of 2021, the Sœurs Jumelles festival was launched in Rochefort, a place where music and images come together. A film concert was held there on June 23 in tribute to Michel Legrand and Jacques Demy.

Geneviève lives with her mother who runs an umbrella shop in Cherbourg. She falls in love with Guy, who is called up for military service in Algeria and leaves the city. The lovers separate, promising each other eternal love. But Geneviève soon discovers that she is pregnant and ends up giving in to her mother's pressure by marrying Roland, a rich jeweler who has long coveted her. When Guy returns to Cherbourg, he discovers Geneviève's marriage and finds his seriously ill aunt who is faithfully cared for by Madeleine, who has been in love with him for years.

Michel Legrand, jazz musician and composer extraordinaire, has left his mark on the history of cinema, including the films of Jacques Demy, especially The Umbrellas of Cherbourg, the 60th anniversary of which is being celebrated in Cannes. Using never-before-seen archives and personal accounts, the film looks back on a lifetime dedicated to music, and the career of a man who served it masterfully to the very end.
