A Jesuit missionary and Abasan, an Indian convert of his, are tortured by a tribe which resents their teachings. Some simple miracles, however, overawe the Indians and the missionary and his disciple are allowed to continue their work. Among those whom they win over to Christianity is Monoka, a beautiful Indian girl, whose sentiment becomes divided between the new religion and love for Abasan. Monoka's mother is a witch. She invokes a hideous spirit which visits the girl and puts her under a spell. Monoka is stricken blind. The medicine man is called in, but he can do nothing. The priest and Abassan drive away the evil spirit and restore the girl's sight. Soon after this she is dragged off into the mountains by spies of the witch who fasten her to a rock to perish if she will not renounce the Christian faith. Several days later the Jesuit and Abasan find Monoka in the wilderness. They arrive just in time to save her from death. Monoka and Abasan are married by the priest.
