Antonio asks his godfather Don Luis, who owns a ranch, for help to convince his father, but everything is useless. Antonio argues with his parents, who threaten to take away his word and, of course, his money, but he, determined, leaves and takes with him Lucinda, a young orphan and without money with whom he is in love. On the first occasion he throws himself into a spontaneous bullring where he triumphs, but when he is making the last pass, he suffers a catch. At first he doesn't seem serious.
