A Broadway composer, Bluestone, who has just died of a heart attack is visited by "Prince", who gives him one wish because of his contributions to entertainment. Bluestone wants to relive a youthful encounter with the girl of his dreams, Mary Ellen Kasgrove. When he returns to the high school party, nothing is as he remembers it but one girl, Teresa Golowitz, sits by herself. Prince, in a girl's body, reminds him that Teresa committed suicide that night. Bluestone gets her to sing and convinces her to meet him the next day. When he returns to the present, Bluestone finds out that Teresa went on to become a famous singer and that because of his interference he won't be going to the "higher place". He and "Prince" head off to lower fields to prepare some entertainment. In the far future an expedition returns to a desolate barren Earth where a scientist begins to see the ghosts of those who died years ago.
