When a young Christian college girl named Teresa is introduced by her Spiritual Formation professor to the writings of a young mystic girl from the 16th century, Teresa of Avila, the 21st century Teresa's life is dramatically affected as she plunges into mysticism. As the young girl falls deeper into the grips of this dark spirituality, a young mysterious man and Teresa's concerned foster grandfather, who graduated years earlier from the same school, see what is happening to the young girl, and they make plans to rescue her.
