Padre Augustine of the Capistrano Mission, an accomplished musician, rescues a lovely little Spanish girl from a brutal father and adopts her as the child of the church. She becomes an accomplished organist, but elopes with a good-looking good-for-nothing Phillippi. She pays the penalty of her folly, and eventually leaves her abuser and returns to "sanctuary", to solace by her music and finally saves the mission and the pious Padre through the same ministry.
