When a sixteen-year-old Spanish girl sees a religious vision while praying in a convent, she becomes involved in a series of humorous adventures.
Catalina is a crippled girl, supposedly cured by divine intervention after witnessing a vision of the Virgin Mary. As a result of this, she is pressured into becoming a nun in a Carmelite convent. The Bishop of Segovia, himself undergoing a crisis of faith, becomes involved in the debate about the debt owed to god by Catalina for her cure, but the girl resists all attempts to control her life, determined to marry the man she loves. She joins a troupe of strolling players and becomes the most famous actress in all of Spain.
