This ghost story, set at the turn of the century, centers on the plight of elderly dowager Marianna, who is tormented by the alleged specter of a young man roaming the corridors of her mansion. After spotting a face in an old photograph that seems to match the old woman's description of the "visitor", Marianna's sister decides to check things out and see if any of this is for real.
