Catalina is the story of Catalina d'Erauso, the 'Lieutenant Nun'. When Catalina's beloved older brother Miguel is sent to the New World to see to the family's fortunes, Catalina has only one wish: to follow him. She begins her quest by earning her education in a convent. And then, one day, she leaves. She cuts her hair, dresses in men's clothing, and becomes Francisco. Catalina develops and internalizes her new identity as a man so thoroughly that she convinces not only everyone around her - including her lovers - but eventually even herself. Her path leads her from San Sebastian to New Spain, Chile and Peru. It is the story of a despairing quest for the other - and for one's self.
