Cléo is an artist, a young eccentric who talks to her hat and keeps gummy bears in a gun holster. Because of her oddities, she feels like an outcast and a misfit. Corentin-Naël is a lonely old man, abandoned and forgotten by his children.
Together, Cléo and Corentin will meet by chance on one of Paris’s many bridges, encounter Renoir and Monet, converse with Jules Verne and the Parisian bohemians, spend a night beneath Van Gogh’s stars, and realize that they are not alone in this beautiful and wonderful world.
