En route to the celebration, the forces of the Aztec underworld cause Diego's car to crash, ending his life. Diego awakens in the Aztec afterlife of Mictlan where the god of death sacrifices him to Tezcatlipoca in a ritual where his heart is torn from his chest with the aid of an obsidian blade. He is then sent back to the land of the living exactly one year after his death. Diego, selected long ago by the Old Indian, is the sacrificial priest in service to Tezcatlipoca. In order to fulfill the prophecy of the Sixth Sun, Tezcatlipoca requires three human sacrifices, each symbolizing the Catholic Church that wiped out the old gods over five hundred years ago. And Maria, being the direct descendant of the Somera family is at risk. Armed with the power to take life or restore it, Diego must struggle against the very gods who created him in order to save the woman he loves.
