Professor Samuel Hale Constable is a government expert in the field of cybernetics. He and his wheelchair-bound wife Lenore became parents late in life, only to lose their daughter Mary before she reached adolescence. Now their daughter's spirit seems to be reaching out to her grief-stricken father from beyond the grave, encouraging him to give up the important project on which he's been working.
