Scooby and Shaggy win an essay contest to have dinner with Vincent Van Ghoul. When they arrive at the mansion, they are attacked by monsters that seemingly came out of Van Ghoul’s movies. Not only that, they are attacked by a monster who calls himself Nightfright (which does not belong to any of the actor’s movies) who states that he wants to kill Van Ghoul. This causes Van Ghoul to reveal that he had used the essay contest to start a new TV show and that Nightfright is not part of it. Trying to escape only to find out they are locked in and cannot leave until morning, Shaggy calls the gang and they come to help the three, in hopes of finding out why Nightfright is really after Vincent Van Ghoul.
