Padre Dominguis, the village priest of a quiet little spot in old Mexico, has been on a visit to the daughter of his dead sister and is about to return to his charges. He is much surprised and more than a little pleased to find that his niece is in love with John Brown, a progressive American, who has settled among them, for the Padre is a broad-minded man and knows that Mexico needs the influx of American energy to make her a great country.
