Aurora Fernandez, a poor Cuban girl, is persuaded against her will to become betrothed to Don Armada, a wealthy Cuban. She loves Pedro, a young fisherman, who lives with his uncle, Father Venture, and his sister Celida, who has been secretly stealing to Don Armada's villa, but is cast off by him on his engagement to Aurora. Longing for a sight of Pedro, disguised as a dancing girl, Aurora goes to an inn where Pedro comes with other fishermen for a nights revelry. He does not recognize her as his "Lady of the Lily" as he calls her, but falls a victim to the charms of the dancing girl. Celida, dying of a broken heart, confesses to Pedro and Father Venture, and Pedro, to avenge Celida, summons all the fishermen in the village and leads them against Armada in whose villa the wedding feast is being held. The guests fly in terror and Armada is wounded.
