In the weeks before the 1979 Mexican elections, San Diego P.I. Alvaro Hickey is checking the stories that Baja California campesinos are spreading about visits from the Holy Virgin, one who has definite political preferences. Though Alvaro doubts that this visitor is divine, he's firmly on her side. Then, Lourdes Shuler asks him to unite her with her sister, Lupe, whom she claims is the campesinos' Virgin. Alvaro is not the kind to turn down an appeal for help, especially from such a beauty, even though she may be hiding something. But he doesn't know about the infamous comandante of the Mexican federal police who has come from the Capital to rid the land of this vagabond Virgin.
