An exuberant tale set among the flashing rhythms, intoxicating smells, and bewitching colors of the carnival. The holy icon of Saint Barbara of the Thunder is bound for the city of Bahia for an exhibition of holy art. As the boat the bears the image is docking, a miracle occurs and Saint Barbara comes to life, disappearing into the milling crowd on the quay. Somewhere in the city a young woman has fallen in love, and her prudish guardian aunt has locked her away - an act of intolerance that Saint Barbara must redress. And when she casts her spell over the city, no one's life will remain unchanged.
