The windy city is home to the hit TV show, Talent Star, in which songwriting duo Fred Jones and Daphne Blake are finalists with some high hopes. Not to be left out, Scooby-Doo and Shaggy Rogers have a secret act in the works, which they are betting will take the contest by storm. Unlucky for them, the competition is frightful at this talent contest as the show is being broadcast from an opera house with a history of horrors and a particularly vengeful phantom that has cursed the show's production. From costume changin' chases to collecting creepy clues, the show must go on.
