Bachelor Chester and his spinster sister, Louise, are summoned from Ohio by a "mystery man" who instructs them to visit their Uncle Abner in New York City. A miserly recluse, Abner lives in an old house where he has gathered a strange collection of people: Brown and his wife Gladys; two untrustworthy servants; the mystery man; and Thelma and Joe, two young people on the track of a missing diamond owned by Abner. Chester and Louise arrive at the house and are frightened by weird happenings. After much fuss and confusion, the mystery of the diamond is solved, and Joe and Thelma are revealed to be newspaper reporters in search of a good story.
