Pepita, a radiant and merry Spanish beauty, and her playful brother Jose, witness their mother, whose faded beauty led her husband to abandon her for another, plunge a dagger into her breast. After their uncle avenges the death, Pepita develops a fierce hatred of men and pledges never to marry, while Jose leaves for Madrid with a benevolent padre. Sebastiano, Spain's most famous toreador, arrives in town and, after seeing Pepita, spurns the pretty Sarita, who dies hopelessly infatuated. Later, Pepita visits Jose in Madrid and encounters Sebastiano. She resists his attempts at conquest and haughtily makes him serve her. Finally, when Pepita responds to Sebastiano's protestations of love with vehement hatred, he leaves for Lisbon. His departure awakens Pepita's love, and when he returns with a fiancee, Pepita suffers intense jealousy. During a bullfight, Sebastiano glances at Pepita and is gored by the bull. As he is about to die, Pepita, ready to die with him, declares her love, and Sebastiano revives.
