The gang stays at a housing estate next to a graveyard during their spring break in New Orleans. They soon realize that two Civil War ghosts re-enact a duel every night to scare away guests. Daphne is later kidnapped so it's up to Fred, Velma, Shaggy and Scooby to find her and uncover the truth.
This episode includes examples of the following tropes:
- Bound and Gagged: Daphne is given this treatment after being kidnapped by the ghost brothers. Eventually, she's found and freed by Scooby and Shaggy.
- Cut Lex Luthor a Check: The culprit has access to projectors that display very realistic images of the ghosts, and would make a fortune if he used his designs in a haunted attraction or theme park. Instead, he uses it to con tourists out of their money.
- Imposter Forgot One Detail: Velma notes that the ghost brothers that chased them couldn't be the real thing because of their height. One of the real brothers was taller than the other, while the imposters were the same height.
- "Scooby-Doo" Hoax: A different variation, where the culprit simply uses harmless projections to con tourists. However, when the gang was getting closer to discovering his scheme, he and his assistant dress up as the ghost brothers stop them.
- Villain Ball: The culprit uses his realistic images of the ghost brothers to con tourists when he could just use them to make an honest living through haunted attractions. Instead of coming clean about it when the gang was close to discovering the truth, he and his kidnap Daphne to try and hinder the investigation. Now they're charged with kidnapping alongside their con.
