As described in a film magazine, Moctezuma (Hatton), the Aztec king, resents the intrusion of the Spanish who have come to convert the Aztecs to Christianity. As Tecza (Farrar), daughter of the king, loves Alvarado (Reid), one of the Spanish captains, she allows the Spanish soldiers to enter the palace. After a terrific battle, she is the only surviving Aztec and the Spanish allow her to depart in peace. Alvarado then comes wooing the last of the Aztecs and wins her.
