Susanna, a parapsychology student with whom he is in love, tries to help him interpret the paranormal warning messages he is receiving. When Luciano turns out to be haunted by a mysterious killer who calls himself "The Guardian Angel", Susanna discovers that Luciano's paranormal powers are not real at all.
