The Gothic prince Ranimiro and his daughter Amaya have been taken prisoner by the Basques. He will be tried by the Council of Elders, while the Basque leader Íñigo, who arrested him, falls in love with his daughter Amaya, unaware that she is the current owner of the golden bracelet that symbolizes Basque tradition and that, according to legend, the man who marries her will be proclaimed king of Vasconia.
