Christmas in New Orleans may not be particularly festive in the Derringer household this year, since Yancy's Uncle Henry Spinner, a government engraver, has been murdered and the plates for the new hundred-dollar greenback he was designing have disappeared. While Yancy searches for the murderer, his old hound-dog Dixie shows up at this family seat along with the news that the dog is the only one who can lead Yancy to where the family treasure is buried. The episode ends with an impromptu Christmas party attended by most of the series' recurring characters.
