The Ghost of Christmas Never was the disguise of Nanette Musette, the housemaid of Winslow Neckleby. She wanted to steal a valuable emerald hidden in the children's home inside an antique nutcracker ornament. The Scooby-Doo Detective Agency arrived at the home to aid in their Christmas pageant.

The ghost first appeared in a rehearsal, while Shaggy Rogers acted out the part of Ebenezer Scrooge. At first the gang suspected Mr. Neckleby himself. On a visit to his house, both they and Nanette overheard the reading of a will. This led them all to believe the emerald was in a star in the attic. A chase ensued, during which Scooby-Doo, Shaggy, and Scrappy-Doo captured the ghost. However, it got away and the star was empty.

Finally, at the pageant, everyone realized the emerald was in the nutcracker. The ghost jumped on stage and snatched it off the Christmas tree. After stealing the nutcracker, she led the gang on a chase with her in a sleigh and the others on skis. The chase ended when the sleigh crashed and the ghost was unmasked to reveal Nanette, who was then arrested.
