Sylvia Lee, a young American in Spain, is torn between her attraction to dashing revolutionary Pedro Pezet and her American boyfriend, Reginald.

Spanish revolutionary leader Pedro Pezet, who serenades American Sylvia Lee, visits a café and stops the advances of a colonel to Carmelita, a dancing girl whom Pezet has loved. After Carmelita warns Pezet that she will knife him if she sees him with Sylvia, she intrudes on their parting embrace and cuts his hand as they struggle. Meanwhile, Sylvia's bumbling American fiancé, Reginald Van Ransen, visits, providing an unwelcome surprise to Sylvia, who loves Pezet. After Sylvia breaks off their engagement and goes to the hills, Carmelita, whom Pezet has since rebuked, obstructs his plans to abduct the governor during a parade. In the ensuing chaos, Pezet hides in Reggie's car and forces him to drive to the hills, where they find Sylvia. After Reggie beats Pezet in a fight, he realizes Sylvia's love for Pezet and returns Pezet's revolver. Reggie follows them to the revolutionary's headquarters and overhears Pezet's plan to hold Sylvia for ransom. After Reggie saves Sylvia, Pezet escapes and is stopped from committing suicide by Carmelita. They acknowledge their mutual love, as do Sylvia and Reggie.—Pamela Short
