Master confectioner and benevolent witch Vianne Rocher trades the quiet life of Lansquenet-sous-Tannes for the crowded streets of Paris. Cloaked in a new identity, that of widow Yanne Charbonneau, she opens a chocolaterie on a small Montmartre street, determined to still the wind at last and keep her daughters, Anouk and the baby, Rosette, safe. But soon the weathervane turns ... and into their lives blows the charming and enigmatic Zozie de l'Alba. And everything begins to change.
