Rosario, the daughter of a rancher, and Antonio, who comes from a poor family, have been friends since childhood. Before thinking of marriage, Antonio, ambitious and daring, leaves in search of his fortune and a social position which will please his loved one's family. Two years later, with Antonio away and her father dead, Rosario falls into a trap set by a rich suitor, the owner of a neighboring ranch, who, to facilitate a marriage between him and Rosario and combine the two properties, bribes the secretary to the court to alter the father's will. When Antonio returns, with a small amount of money saved, he exposes the crook and regains his sweetheart.
