After years of unmasking fake ghosts, the Mystery Gang have separated and acquired new careers, including Daphne being a reporter. For her birthday, Fred invites the whole gang to join their trip to Louisiana for Daphne's television show. They have many adventures but every ghost is just a villain in a costume. They soon meet Lena Dupree, who takes them to Moonscar Island in the hopes to encounter a real ghost. Things soon become creepy and the gang find themselves caught between vicious werecats and zombies lead by the ghost of Moonscar the Pirate.

When Scooby and the gang get trapped in a video game created for them, they must fight against the 'Phantom Virus'. To escape the game they must go level by level and defeat the game once and for all.
